Panty Charmer

"Panty" (pronounced pan-tee) refers to a woman's underwear. A Panty Charmer is a person who flirts with, and gets along well with women, regardless of whether or not their aim is to get into their panties.

This term is similar to lady-killer, but it is less insidious.

Jill: *discretely reports Mike to HR*
