A Dirty Curty is similar to a
Dirty Sanchez, however when doing a
chick doggystyle and sticking your finger up her ass, one does not give the
chick a reacharound shit mustache but instead he gives himself the shit mustache.
Dude, we could see Joe railing this
chick from behind through his bedroom
window, and he totally
stuck his finger in her ass and gave himself a Dirty Curty.
