2. If you get a low test score
3. If you are a faggy fuckfaced shithole eating anal grease sucking buttfucking shit raping douche-waffle-mc'cunt-nugget, then you can use this to describe your friends if they do something that they weren't even trying to succeed at
4. A person disses you and you are such a fuckhole that you can't think of a diss you may use "fail" here.
2. I failed on the test today.
3. Kid accidentally trips
Faggy douchebag shitfucker: You Fail!
4. Kid calls you an inside-out asshole licker
Inside-out asshole licker: You Fail!
* Please if you really want to be a good friend tell your retarded shit-eating friends to stop saying fail, seriously nearly every one of my friends say this and I hate calling them shit fuckers, but I have to so someday they will get some sense and look back at their retardedness and say "Why did I use to say fail, God I was a regurgitating asshole"
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.
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.
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.
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!
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.
(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.)
