dirty justin 

When having sex with a girl you turn her around like doing a doggie style but instead of inserting your penis you insert your nose in her ass and have her lick it afterwards.

Man, I just gave that girl a Dirty Justin. I don't know if my nose still stinks from her mouth or from her ass.
