Fission Mailed

Originated from Metal Gear Solid 2 Sons Of Liberty. What is different is that they changed the first two letters in order to confuse the player. Sometimes used on messageboards to show defeat or total pwnage.
"That sign said Mission Failed so I turned the power off."

"Dude, it was Fission Mailed, they just tried to confuse you, now you gotta start all over again cause you didn't save. Pwned!

FISSION MAILED

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.

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.

Considered to be part of l33t sp33k. Gaming slang. Often used as the end of a sarcastic comment.

The word 'flag' as pronounced by people with thick Belfast accents. The term is a perfect encapsulation of the disproportionate and overblown reaction to the removal of the Union Jack (as in 'de fleg') from above City Hall in Belfast. Where previously it had flown for 365 days per year, it is now flown on 17 designated days of the year - in line with many other British cities.

The event caused a portion of the Protestant community ('fleggers') to make international pricks of themselves as they proceeded to wreck the fucking place, claiming it was another erosion of a 'British' identity they perceive to have been under attack since the horrifying spectre of equality reared its head in Northern Ireland.

The word 'fleg' - and indeed 'fleggers' - fittingly describes a section of humanity unconcerned with knowledge, reality or the vagaries of the English language. Like America's tea-baggers they are ruled by instinct, fear and paranoia with a side dish of rampant bigotry and startling ignorance of the world around them.
"Wat de fuck like! The taigs got de fleg took down! Let's wreck de fuckin place! No surrender!"

"De fleg has been took down! Before ye know it there'll be a united Ireland! Attack Short Strand! God Save The Queen!"

To take something small, that doesn't quite qualify as a theft. Probably from the Danish "skæv" or the Dutch "scheef", both of which are pronounced similarly, meaning "askew, or not quite right'. To change an item's ownership without permission, but only something small and of little worth.
"I skeefed an apple off the neighbor's tree." "I skeefed some chips outta your bag when you looked away." "Don't skeef my chair when I go to the bathroom."
