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.)

1. If you do not succeed at a goal that you were going for
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.
1. I failed at getting the job that I wanted.
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"
