Firecracker Fart
Normally occurs at the tail-end of an upset-stomach deuce. When you fire off a bunch of quick-hitting farts, in a firecracker pattern, with no substance or stink with the sound being amplified by the toilet bowl.
HeJohn says to HimDavid, "Stay away from the taco-truck today, just took a hot'n'steamy logger with the Firecracker Farts encore at the end!"
