How to use the term
TB:

It's TB Thursday, y'all know it's time to embarrass ourselves with these middle school selfies.
Um... I know you saw my message. Can you, I don't know, like TB sometime before the apocalypse?
Doctor: We're running tests to rule out TB.Patient: Oh thank you doc, thought my coughing was only a result of vaping non-stop.

TB: From Nostalgia to Nagging (and the Occasional Cough)

No, dear grog-addled sailors of the meme seas, we're not merely boarding this vessel for lung infections this evening (though we shall briefly dock there). Tonight, we explore an abbreviation slimmer than your wallet after avocado toast brunches—'TB'.

The Nostalgic Charm—TB as 'Throwback'

The illustrious 'TB' stems primarily from the social media ritual of nostalgia, casting minds back to yesteryear with an array of ancient selfies, childhood photos, and vintage friendships that once set Tumblr ablaze. Especially popularized through hashtags (#TB or #ThrowbackThursday), it spread rapidly across networks like Instagram and Twitter, becoming a weekly homage to the ghosts of questionable fashion choices and tragic hairstyles past.

Origin: Rose to fashionable prominence circa the early 2010s alongside the dramatic explosion of social media sharing.
Usage: Practiced diligently by Gen Z, Millennials, and even the occasional bewildered Boomer wandering the digital landscape.

A Plea for Attention—'Text Back'

In a slightly more anxiety-inducing turn of fate, 'TB' also serves as shorthand to passive-aggressively remind your dear friends (or unfortunate lovers) that your last text message remains unanswered—hovering in digital void, whispering 'hey, still alive over here'. Primarily wielded by impatient texters, romantically vulnerable teens, and needy individuals waiting on Snapchat.

Common amongst Gen Z and younger Millennials, perpetuating digital etiquette anxieties.
May provoke defensive eye-rolls or the occasional technology-based confrontation.

The OG meaning—Tuberculosis

Long before gaining modern-day slang currency, TB meant one thing and one thing only: tuberculosis—the formidable respiratory disease. Not nearly as socially palatable as nostalgic selfies or romantic desperation, but historically important nonetheless.

Origin: Medical jargon dating back to 19th-century sanitation nightmares.
Cultural Significance: Illustrated famously in literature and opera alike. (See Puccini's tragic heroine, Mimi, who succumbs melodically to TB.)

Variations and Alternative Spellings:

#TBT (Throwback Thursday)—specifically used for Thursday reminiscing.
TBTB—Text Back To Back, indicating ongoing texting without pause.

Cultural Evolution, Controversy, and Confusion

While 'TB' regarding tuberculosis remains grimly consistent, the social meanings spawned varying degrees of digitally induced anxiety and overuse. Critics may occasionally lament TB's nostalgic subversion of medical severity, or sarcastically remark on users desperately awaiting replies. Despite potential confusion, context always triumphs: National Geographic rarely posts about nostalgia using disease abbreviation (unless reference to vintage pandemic photography).

In conclusion, however one sails these slang-infested waters—from choke-inducing disease to existential dread of being ghosted—'TB' encapsulates it all with the brevity and ambiguity modern slang thrives upon.
