smegma joint 

After a woman/girl wipes after peeing or pooping with toilet paper...a little piece of t.p. is left behind either in the labia or on the floor and has the distinct look of a joint and is mixed with smegma. Sometimes found in your underwear. smegma shmegma

I was waxing this ho and there was a smegma joint in her labia. I almost gagged.
