Demystifying Blu – A Deep Dive into the Meaning Behind This Ubiquitous 3-Letter Word

At first glance "Blu" seems simple – just a shortened form of the color blue. But when you look deeper, this compact 3-letter word carries a surprisingly rich and nuanced range of meanings. As a long-time tech geek and pop culture junkie, I‘ve seen Blu pop up everywhere from wedding rituals to laser discs. In this in-depth guide, I‘ll provide the definitive history of Blu and break down its many facets – from baby names to military slang.

The Complex Etymology of Blue – A Color That Defies Easy Description

Before we can understand Blu, we need to explore the long and winding history of the word “blue” itself. Believe it or not, the origin of this common color name is quite complex! Trace it back through Old French to the Latin "blavus" and you‘ll find associations with terms like blond, yellow, and the word "bleach." Related words like "blaeu" in Old Frisian gave us the modern Dutch "blauw."

So how did a word tied to blondness become our word for the cool end of the spectrum? Linguists point to the tricky nature of early dyeing methods, which made reproducing rich blues very difficult. Thus the slippery definitions. Even the great Shakespeare called the ocean the “blue-veined” deep, evoking those hints of green in deep blue waters.

So in a sense, Blu captures the elusive, enigmatic essence of blue more aptly than the full word!

Blu Takes Off as a Given Name – Pop Culture Namesakes from Music to Hollywood

Once it evolved as a compact form of “blue,” it didn’t take long for Blu to catch on as a stylish short name for babies. By trimming off that final vowel, Blu became punchy, brisk and eminently Instagrammable (looking at you, Beyonce and Christina!)

The pop culture credentials of Blu as a baby name grew longer by the year:

• Musician Blu Cantrell delivers R&B hits like “Breathe”
• Actor Famke Janssen names her son Kip Blu
• Rapper Blu gives us party anthems like “NoYork!”
• The trippy cartoon Foster’s Home for Imaginary Friends features Blu the blob

Plenty of mom bloggers gushed about how the name is “utterly cool” yet “distinctly feminine.” Blu also appeals to parents who want something modern but not TOO out there (like naming your kid after a fruit).

So don’t be surprised if a baby Blu shows up in a stroller near you soon! The name spans cultures and gender – equally fitting for boys and girls.

How Blu Became Central to the Digital Media Revolution

Of course most of us associate Blu with groundbreaking digital technologies, primarily:

Blu-ray

As many readers probably know, Blu-ray discs represented a massive leap in home entertainment thanks to blue-violet lasers that could store far more data. The name telegraphed both high-tech style (lasers!) and huge capacities (ray!).

Blu-ray overcame the messy format wars of the early 2000s to convincingly trounce HD-DVD. By mid-2008, Blu-ray had claimed the throne as the high-def physical format of choice. With its compressed title, Blu-ray exemplified the convenience and portability coming to define 21st century tech.

A bit of trivia – did you know “Blu” was partly an homage to old laserdisc formats like CD (compact disc) and LD (laserdisc)? The makers of Blu-ray discs embraced this tradition with its futuristic brevity.

Blu Phones

Carrying on the high-tech associations of “Blu”, this plucky upstart aimed to make smartphones affordable for the masses starting in 2009. The company lived up to its name, boldly undercutting giants like Apple. As someone who remembers shelling out $600 for an early iPhone, I cheered this defiance (thoughApple still gets my money today, I admit).

But Blu Phones also proved remarkably prescient – predicting the rise of value brands like OnePlus. The name itself aligned perfectly with this image – casual, upbeat and everyman. Far better than calling themselves “Discount Phones Inc” or something boring like that!

So in the world of tech, Blu built up great brand associations – innovation, accessibility and fun.

When Feeling Blu Has Nothing to Do with Tech

Of course, long before it entered the popular lexicon via consumer electronics, Blu had another common meaning:

Feeling blue – aka sad, depressed, melancholy.

This usage apparently dates all the way back to the 14th century. But why is blue associated with sadness? Linguists point to rain and gloom – think of dark stormy skies and "singing the blues." There‘s even an old term "blueskin" referring to dark moods.

Amusingly, people also use "blue" to mean happy and upbeat – as in "blue skies" symbolizing cheerfulness. English is nothing if not contradictory! So Blu neatly captures both sides of blue.

Beyond feeling blue, Blu gained some other slang associations:

• BLU (Boys Love Us) – A flirtier spin on the coy Victorian acronym SWAK (Sealed With a Kiss)

• BLU (Better Left Unsaid) – For risque gossip or topics best kept private

• BLU (Bigger, Longer, Uncut) – Originally a reference to the unedited South Park movie

So the suggestiveness of Blu makes for some naughtier lingo!

Something Blu – Wedding Traditions and Old Wives Tales

Even at weddings, the color blue takes on rich meaning. Most brides know about the old rhyme: "something old, something new, something borrowed, something blue."

This tradition dates to the Victorian era and a time when blue remained an expensive dye. Thus blue items represented prosperity. Queen Victoria herself wore a blue gown at her wedding.

Some also believe blue symbolizes faithfulness, sincerity and wisdom. Makes sense when embarking on the solemn vows of marriage. Plus blue garter belts became a staple of honeymoon lingerie for that oh-so-important wedding night!

Beyond weddings, folklore gives blue various meanings:

• If a bride sees a lone white horse on her way to her wedding, good luck. But if blue – uh oh, she‘ll take a tumble.

• Eating black eyed peas on New Years ensures wealth. But wealth and love come to those who eat 12 grapes at midnight – as long as you make sure to wear blue undies!

Superstitious? Maybe – but these traditions show how deeply ingrained the color blue remains across so many realms of human life.

When Blu Takes on a Whole New Meaning – Tech Jargon and Secret Codes

While most of us think of Blu in terms of entertainment and baby names, it has some very specific technical meanings as well:

BLU-109/B

This intimidating name refers to a bunker buster bomb utilized by none other than the US Air Force. The shorthand Blu name gives it a deceptively peppy sound for such a fearsome weapon.

This reveals how military tech abbreviations often cross over into popular lingo. SCUBA, laser, radar – these terms sound cool before we realize their deadly serious origins.

Secret Squirrel

In military slang, “Secret Squirrel” refers to black ops agents involved in highly classified missions. Their real identities and objectives are on a strict need-to-know basis only.

It may seem comical, but again we see how government tech abbreviations get playfully distorted in military speak. And from there seep into pop culture at large.

ILY, SWAK and More – How Blu Fits into the Evolution of Text Slang

Lastly, the rise of Blu reminds me how texting and messaging gave birth to a whole new vocabulary of shorthand.

Going from “I love you” to “ILY” or the numerals “143” allowed texters to save time and taps. Similarly, “SWAK” (Sealed With a Kiss) let Victorians discretely encode flirtation in their letters.

Adding Blu to the lexicon follows this age-old tradition of squeezing big emotions into bite-sized lingo. Love in the time of texts and tweets must be concise!

So in many ways the journey of Blu mirrors the evolution of language itself – endlessly fluid, contradictory and full of hidden byways ripe for exploration by the intrepid linguist!

Conclusion: How One Compact Word Captures the Full Breadth of Blue

What seems simple on the surface often reveals untold depths upon closer inspection. So it is with Blu.

Initially just a compressed form of “blue”, Blu went on to permeate every corner of our culture – from Tinseltown to the Pentagon. It anchored innovations that reshaped society while also encapsulating timeless human experiences like love and melancholy.

So next time you see Blu flash by in a text or brand name, take a moment to appreciate the layers of meaning in this diminutive word. Great things truly can come in small packages.
