Dirty Griffin

It is a Dirty Sanchez, but instead of a mustache, you give the person a unibrow with your shit covered dick.

To spice things up, Bill gave Terry a dirty griffin instead of the usual dirty sanchez.

Dirty Griffin

A 'dirty griffin' is when a guy is fucking a pregnant lady and claims to have had a threesome.

"Did you hear that guy had a dirty griffin"

"Yeah, it was his mates mum too"
