Mahoney

typically a short man, whom you're not certain is either giving sly look or just has a persistent squint.

Legend among men, but unfortunately has an anus the size of a dinner plate *
Enjoys a munch on phallic shaped objects, but you'll look past it in hopes he'll come to terms with his selective eating.

"Can't go out for dinner with a Mahoney ever again"
"Ikr too many penises on one plate"
