The fatter and uglier friend of a grenade. Often brought along to make the grenade feel that she is not the ugliest girl at a party. The main purposes of the grenade launcher is to cockblock, instill fear, provide backup in a fight and to purposely rile up the grenade into exploding the chances of sex for everybody. Popularized by Mike "The Situation" from the MTV hit series Jersey Shore.
Its bad enough that this cutie brought a grenade with her, but this chick also brought a god damn grenade launcher as well. I personally try to avoid grenade launchers, at all cost. Not worth getting my GTL on for. At all.
