Oh My Fudge Goggles Forgot My Lunch.

Use this term when you've forgotten your lunch, instead of shouting out abuse when teachers/co-workers are around.

Gary: What have you got for lunch?
Bob: *looks in his bag* omfgfml!
Gary: Here have a cupcake :D

OMFGWTFBBQHAX 

Short for 'Oh my fucking god, Barbeque Hacks'.

A random term often used in many games such as the Warcraft III game, DotA (Defense of the Ancients).

It is usually used after getting killed and/or can be used as an accusation that someone is hacking, cheating, exploiting or playing unfairly in the game. (e.g. maphacking)

Tatsumaki has activated anti-hack. Their may be some brief lag for a period of time and any players who are hacking will be removed form the game.

Rjay has left the game.

cdp has left the game.
