Conrad asked me about the Greek letters on the houses we passed on our way home from camp. I told him about fraternities, and why some people liked them and some people didn’t. I tried to describe what a raucous fraternity party was like “without saying “orgy””. But “frat party” is pretty much the best simile for an out-of-control party. So I told him that, and he joined me in trying to come up with a different one.
His suggestion: “An out-of-control bar mitzvah.”
