A Boo Boo Party occurs when two or more people occupy stalls to simultaneously take a shit in a public restroom.
Kenny ‘The Jet’ Smith: Hey, Shaq! I have diarrhea! Is that you in this bathroom?

Shaq: Yeah! I’m taking a shit from all this BBQ chicken...

Kenny: Well, we’re about to have a party! Do you what kind of party that is?

Shaq: IT’S A BOO BOO PARTY!!!
