Waning Mullet

a man’s hairstyle that is bald on the top but with long stringy hair hanging over the collar in the back (elderhostel up front, party in the back)

This is a modification of the 80’s mullet. It is worn by the diehard that refuses to give up the long hair that he sported back in high school.

Bob: Did you see Jim Rickards on Fox Business talking about the demise of the US Dollar?
Dave: Is that the guy with the waning mullet?
Bob: Yeah, that’s him.
