A term loosely meaning that you have been embarrassed to the highest degree, similar to pwned and You Got Served

Origin: Metal Gear Solid 2 near the end of the game, there's a screen that says that very phrase that's supposed to mimic the "Mission Failed" message you get when you normally die in said game.
Dude, your girlfriend sucked my cock last night! FISSION MAILED!

Derives from the game "Metal Gear Solid 2"

it means "Mission Failed". which is used as a derogative term to slander someone/ someones argument that they've put forward in a debate, it is both patronizing and shows that you're putting an end to the argument.
