Plop Splash
The term given to when one's poop is dense and heavy enough to cause a plop, in the toilet, that results in one's butt to be splashed. It's a commonality that one becomes panicked as to why their butt has received a wet surprise, that is, until they remember their Chinese feast the night prior.
"Aww, dude, what the hell was that!?... God damn plop splash, fucking General Tso's gets me every time."
