When someone gets blood on their fingers and wipes a mustache on someone's upper lip.
Brittany did not tell me she was on her period before I finger banged her, so I gave that bitch a Dirty McGee.

Get the Dirty McGee mug.
When a man ejaculates in a girl's ass and some else licks it out
Gil fucked lexi in the ass and came in it then some other dirty whore licked it out, man i wish i was there, i would have loved to see that dirty mcgee taking place.
