When, on a vacation for example, a large group of people who are forced to share one bathroom happen to take a dump into the same bowl consecutively, resulting in a funky mix of everyone's sauces that can only be described as a chocolate potluck.
Mike: Hooo, crap, man, that's some gnarly stank there in the bathroom. Who used the crapper?

Jim: Donna, Elyse, Alex, RJ, Sam, and Frank. Just in the last thirty minutes.

Mike: Well, I might as well add to the chocolate potluck.
