look up any word, like lemonparty:
(v.)- This occurs when one takes a dump and it shoots right out of the anus like a rocket and sinks to the bottom of the toilet bowl, hence the term "scuba." One usually does not have to wipe after this furious anal blast because the exit was so clean.
Your poop scuba dives to the bottom of the toilet bowl and there is no need to wipe, hense Scuba-Shit.
