An extremely cruel yet hilarious prank to play on somebody, where you give them a sundae and they have diarrhea so hard it almost breaks the toilet. The sundae is made like any other sundae, except it contains crushed up laxatives and crushed up stool softeners. Causing the "Victim" or "Target" to have very liquid, very forceful shits, causing them to (Sometimes) shit themselves.
Dude 1: Yo, I just gave Josh an Assplosion Sundae!
Dude 2: What's that?
Dude 1: Just watch.
Josh (Eating Sundae): Oh shit, I gotta shit HARD!! (Runs towards bathroom) Fuck! I can't hold it in! (Shit oozes out of bottom of pants)
Dude 2: Dude, that's evil, but I can't stop laughing!
Dude 1: Fuck yeah man!
