buckstache 

A mustache adorned by fans of The Ohio State University. Sporting a buckstache often leads one to a life of crime and perversion. The buckstache was made famous by the Michigan Wolverine based blog The M Zone. A cousin to the Buckstache is the Warstache, a mustache worn by Auburn fans. The Warstache will lead one to a life of bestiality.

Paul's life took a turn for the worse when he decided to grow a Buckstache.

backstache 

Male back hair which may be manscaped into a decorative form or left au natural. The Fu Manchu backstache is when the tops of the shoulders are hairy, as are the sides of the back (covering part of the shoulderblades), but the center of the back is clean.

So we went to the beach, and Jim took off his shirt to reveal a backstache. It was terrifying in its raw manliness.
