SMG

Acronym for Sub Machine Gun. It is commonly used in the game Halo 3 where it is one of the few duel-wieldable weapons. It features a high rate of fire especially when two are used. Keep in mind that it is a rather useless weapon when used alone. Aim to duel wield.Commonly it is pronounced "Smug" over X-Box live voice chat.

Player 1: Dude grab that SMG

Player 2: F*** yeah
