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.

a sexual act where, during ejaculation, the male furously waves his dick around during the orgasm, creating a "whip" of jizz, all while yelling "Bulbasaur, use vine whip!"

when a guy fucks a girl in the ass before she takes a shit. when the guy is on his way to cum he pulls out and lets the girl take a shit. then the guy ejaculate all over the shit. thus making a dirty dumpling.
