Gooch Rag

Somebody who gives the name douchebag a bad name.
Inspired by the term Gooch
A Gooch Rag is a dirty old rag that is used to clean the gooch area of the body (the part of the body between the Asshole & the testicles).

That guy is such a Gooch Rag!
John that GR stole my business plans!

GR is short for Gooch Rag (and much cooler to use).
