muff coaster

You know when a girl is in junior high and her pubes are out of control and beast like, they get a little matted down from the panties and cotton panel. So if a boy goes downtown for a little action, he discovers the matted down pubes or the muff coaster.

Hey dude, I went to go finger blast a girl last night and it took me forever to get through the muff coaster before I could get to her fun tunnel.
