Butt Brushing

The sexual act of giving someone a rim job while using their ass pubes to floss your teeth. Especially effective for those with braces.

My dentist told me that flossing is just as important as brushing, but i prefer Butt Brushing

butt brush

A vertical strip of hair underneath the lower lip that brushes the taint or the butt crack, depending on the orientation of the owner.

Also know as a flavor saver.

Gina longed for a boyfriend with a Jay Leno chin and a nicely groomed butt brush. Not only would a quality chin-hawk really hit the spot, it would double as a dribble catcher.
