A Muff Buffer is a man’s beard that is more than a 1/4 inches in length. Long enough so that when performing the art of cunilingus the beard tickles the girls Twat and also creates a street sweeper effect cleaning any lint or "Muff Biscuits" that might be there.
A sadistic lesbian sex act, in which sadomasochists improved the act of scissoring to their standards by inserting a Brillo pad between their unshaved vaginas.
First performed in a 70's foreign porno movie entitled, "Beauf De Meauf".
