A way of saying what the fuck or wtf and the same time as expressing your feelings about the event in question being a fail.
Guy 1: Did you hear about Justin Bieber not knowing what German was?
Guy 2: The language?
Guy 1: Yeah man.
Guy 2: Dude, what the fail?!

when you bite through a burger or sandwich but there is something in the sandwich like a pickle or tomato that is harder to bite completely through and you wind up pulling sections of the sandwich out as you take the bite, hence the bite fail.

Getting her horned up to a sloppy wet state for an absolute railing and gut rearrangement only to disappoint her, and yourself for that matter, by failing to achieve an erection and deliver. Usually results in self loathing while watching her flick the bean.
A bottle of Jack was the perfect recipe last night for a rail fail.
I was so horny and ready to just get railed but my uncle drank too much and was like flopping gummy and a real rail fail.
I had to flick my bean to a toe curling orgasm after daddy did a rail fail.

The TRUE highest form of fail known to mankind. Reaching this level of fail means only one thing:
You've failed so much that you have surpassed epic, you are no infinite in your failure and deserve to be put to rest
You've failed so much that you have surpassed epic, you are no infinite in your failure and deserve to be put to rest
Tom - Cena not selling that move was epic fail
Richard - no he has surpassed epic fail, he is infinite fail, he has failed so many times that saying he epically has will be an understatement

A failure so great, one "k" isn't enough. Typically said to people, particularly blond country girls, who are more prone than the rest of the population to such shortcomings.
"Crap I accidently threw my bowl in the garbage!"
"...epikk fail"
"I spelled my name wrong!"
"...epikk fail"
"...epikk fail"
"I spelled my name wrong!"
"...epikk fail"
