Thrown The Fuck Out !
I was TTFOed from my last job. Originated in the wonderful world of Radio DJs and invented by a long time listener when inquiring as to what happened to so and so. "Oh, you mean he was TTFOed ?"

Tears Tears Fuck Off
Computer slang. Often used in Warcraft 3: the frozen throne.

Strictly it is two definitions in one: T_T (tears tears or crying fase) and Pls leave the game of pls shut up.
Used when somebody makes a mistake or something sad happens because some one is noobin'.
Example after a noob mistake:
"TTFO please leave"
