YFCLO 

"Your Fucking Caps Lock is On" Used to online bitchslap people, generally of an IQ approaching room temperature, who type shite in all caps because they think it makes their argument more persuasive to do the equivalent of shouting online.

'Tard: "OMG OMG UR RONG AND RITARDED STFU OMG OMG"

Response: "I offer a rare and not commonly known service.

It's called YFCLO. I surf the internet to warn people when YOUR FUCKING CAPS LOCK IS ON.

Yer welcome.

Oh, and STFU."

YFLOin' 

YFLO and alternatively, Y.F.L.O., though both acronyms for The Youth Foreign Languages Organization., are sometimes thought of as a single question, rather than an acronym. For example, ‘YFLO’ has come to be compared to something like, “Why flow?” The word ‘flow,’ denotes essentially the expression that someone who critiques hip hop, rap and urban music often uses when conveying the notion that a vocal artist, e.g., rapper, lyricist, etc., has verbally flowed smoothly during the vocal artist’s said performance. Lyricists also critique other lyricists’ rhymes to determine if the latter’s lyrics flow. Given that a student’s practice of correctly speaking a foreign language is quite similar to and in many ways comparable to that of ‘bustin’ a freestyle’ or ‘spittin’ dope rap,’ one might be compelled to ask not just a lyricist, but also a linguist-in-training or a foreign language student if he/she can flow or is ‘YFLOin.’ Evidently, this expression was first coined such by Y.F.L.O. student-researchers familiar with urban lingua franca.

You shouldn't've found this word... you have reached peak boredom, you typed out the prime number characters on a DVORAK keyboard. You're probably in class right now and you're supposed to be working, but instead you probably pulled up a layout of the DVORAK keyboard and typed this. Go do your work.

John: "Gee whiz, James, this math task sure is boring!"
James: "I will pay you to stop talking like that."
John: HMM WHY DON'T I PULL UP THE DVORAK KEYBOARD AND TYPE THE PRIME NUMBERED LETTERS, AFTER ALL, THEY ARE UP ON THE BOARD.
John (on computer): yfcludsjm
John (IRL): yfcludsjm
James: HEY GUYS JOHN'S HAVING A STROKE.
