A term used in Call of Duty: Black Ops to describe the cockroaches who use the ghost perk and sit in corners and in grass the whole game, waiting to ambush any one that walks past. They are completely undetected and is the most annoying perk in the game. They take advantage of this and sit in every corner possible in every map because they lack the gun skill to go straight up in a 1v1 gunfight.

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
