That little gay mustache "cool" people have under their lower lip. Aside from asthetic purposes, the "fag mop" is mostly used to capture semen after giving gay oral sex.

Rag Mop is an old Elvis song, sometimes sung in grade school during music class. Well, if you didnt sing this song in school and your friends did, you inevitably called them a Fag Mop.
