Gacid Trip

The act of playing Gary's Mod as a substitute to tripping on acid or playing while on acid.

Guy 1:
My brother Gacid Trips to some weird dancing guy with a briefcase, a traffic cone on his head, and a couple of headcrabs playing twister with a Hello Kitty doll and a bazooka while submerged in apple sauce suspended 10,000 ft in the air shortly before a ROFLcopter did a barrel roll and annihilates his character.

Guy 2: He's gonna be a virgin forever.
