a phrase you hear every secound if you enter a cs (or css) server with many players (about 45 players should do). because every time someone throws a nade, everyone hears "fire in the hole" it doesnt matter where this person stands, you always hear it bacause its a radio command. at first it's annoing but you get used to it fast.
