A creeper, a floating air bisquit. A fart that can not be heard but can sure as hell be smelt. This type of flatulent sneaks up on you and unless there is a breeze, hard to tell who it came from. Don't ever recognize this type of fart out loud otherwise you fall into the rule of: "Whoever smelt it delt it"
