So someone could come up with the modification: BOOTYraceous. I’m almost sure of it.
I bought a book some years ago called Dimboxes, Epopts, and Other Quidams : Words to Describe Life’s Indescribable People by David Grambs. Full of words like this, but it’s at home right now. I like “frotteur”, myself. Someone who likes to rub up against people’s backsides in crowds. It’s good to have a hobby.
