when someone lets a particularly noxious fart, usually in a confined area like the cab of a fire truck, so bad in fact, that it smells as if the gerbils from Richard Gere's ass were performing a trapeze act while suspended from the air conditioning vents.
firefighter 1: dude! you stink!
firefighter 2: oh i know, i'm terrible today!
firefighter 3: JEE-sus! smells like a fuckin gerbil circus in here!
