After having a disagreement with your significant other, it is the act of inserting a finger into an unwashed, sweaty vagina and swiping it across their upper lip.
After a long night of dancing in leather pants, Jane came home to find that Dick had not taken out the trash, so she woke with a dirty sally.
The Dirty Salt Lick is when a male ejaculates and the cum drips down his scrotum and to his butt crack. At this point the opposite sexual partner will then lick the cum from the butt crack. (This will most likely have to have the male in an awkward position in order for the cum to drizzle to the anal region)
"Dude, Becca is a dirty girl."

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
