This is the most extreme version of gastric expulsion from the human anus. Characterised by a loud, thunderous noise, often referred to as the "bass" factor as it will hit anyone standing within 20 or so feet with the percussive blast of the loudest rock concert. Often occompanied by varying amounts of "cackle-berry-juice" these farts can become quite moist and odorous, and at times a quick check is neccessary to determine whether or not any "Mud" was thrown during said release.
"There I was, standing right in front of the whole group when that damn Jambo Rattler snuck up on me and cleared the room."
