The slobber and jizz on a dude's mug when he is done sucking a dick. (Typically used as an insult to describe a friend's face after they pig-out and have food on their chin, etc.)
Bob's grinning from ear to ear, his ugly mug glistening with Oil of So Gay...And he ate the last hot wing, that fat bastard!
