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.

Get the dirty justin mug.
It's a combination of all the "dirties" that could be done to a female while having sex.
Man, my ultimate goal is to perform a dirty cesar on a girl.
