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.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
