A Dirty Gloria is when you get a dirty penis when you are using a glory hole. It usually results in the giver rejecting the penis by not doing anything to it.
Guy: Dude, so the other day, I was kinda feeling like getting a guy off, so I went to the whore house and got a Dirty Gloria!!

Other Guy: Aww man! Sick! You wanna see my dick?
