Reference to a grenade launcher type weapon featured in several warfare silmulation games, both online and offline.
Takes very little skill to use and can kill whole groups of enemies with a single indirect hit, yet the explosion needs to be fairly close.
To be used liberally against elitist gamers who play games all day because they can't get jobs and whenever they can't win they start crying. Much amusement to be had reading their abuse.
Player 1 dies from grenade launcher attack.
