noun- the feeling of shame and embarrassment a woman feels after she hooks up with a man when she decided not to shave or groom herself down there.
Typically the woman will not shave to prevent herself from being slutty but then she decides to shack up with a guy for the night anyways. She then regrets her decision not to shave.

Ashley, "Guess you better hop in the shower and remedy that situation for tonight!"
