Term used to describe a ponytail worn by a man who has gone totally bald on top but not the sides or back of his head. Usually grown to compensate for the baldness in hopes of still appearing virile to younger women. Similar to the comb over, but less obvious.

Commonly found on guys over 40 that work in comic book stores.
