look up any word, like rimming:
 
29.
adjective
1)a: describing any noun or event as having failed; b: the state of being a failure.

2)An internet meme that has become more commonplace in "RL" amongst those of the video game/internet culture.

The use of fail and its amusement are derived from video games out of the common "game over" screens or "mission failure" notifications. Often this is used in redundancy to create a sense of irony: Fail ____ is fail: in which case any noun is thus being identified by the adjective and described by it.
-"God that tank in VOA sucked ass..."
-"Fail DK is fail!"

4.
A rather annoying word whose use in certain situations has greatly increased recently.

Kind of like the word "shit," "fail" is used by people who don't stop to think of a better word to use, making them pretty much useless to society.
A kid falls off a bike.
Douche bag: Fail!
Person that can think rationally: Stop saying "fail" at people who weren't even trying to succeed at anything in the first place.

"Fail" is a word that is more than often overused online. Unfortunately it has spewed into mainstream society and now is being used in every day life, much like "epic".

People who "fail" generally are not even trying to accomplish anything, or they simply do something different than you. This word is most commonly used by annoying teenagers (who put a bad reputation on gaming), who shout "FAIL!" every time someone makes a slight error.

If you point out an obvious flaw by saying "FAIL" you're obviously a failure yourself for having lack of logic.
Kid: I just tripped because someone...tripped me.

Idiot who doesn't use logic to realize it wasn't the kids fault for being tripped, it was actually the other persons fault: FAIL!

To fail is to be either:
Exceptionally bad at something, or to do/say something stupid to people,
Or for an item/thing to fail, it has to not be what it is, such as a funny comic not being funny, etc.
arpgme's comic FAILS
(Therefore meaning that it could be bad or poor at what it is intended to do)

You sir, FAIL.
(The person has just done/written something stupid or supposedly funny which achieves nothing it's supposed to.)

An amazing word that can sum up almost any bad situation in a single syllable.

A bad grade.

Soph: Fail!

I hope I don't get an F on the test.
