monsterfail 

when someone fails extremely hard (see fail) this word can be used.
it is derived of the PC game Unreal Tournament, where a massive amount of consecutive killing led to a "Monsterkill!".

Dude 1: Damn, I got ditched by this chick yesterday even though I was SO sure she loved me!
Dude 2: M-M-M-MONSTERFAIL!

Epic Masterfail 

A fail among fails, the failiest fail in all failness. Epic masterfails can only be executed by an accomplished failure, and usually results in shame, injury, humiliation, death, dismemberment, stds, ect. Epic Masterfails are something usually only witnessed once in a lifetime, so if you see one be sure to tell EVERYONE about it, because you'll never see another.

"Yo dawg George Bush's presidency was such an Epic Masterfail n shit."

Monsterflipping 

mixing molly and acid. Taking acid normally, then snorting a line of molly as you peak. NOT X! the effects of molly and acid are much more intense than those of X and acid, because of the additives included with the MDMA in the exctacy. Monsterflipping is often said to be the only path to psychedelic enlightenment.

dude, monsterflipping is the craziest thing ever. take the dose, then bomb the line after, its awesome.
