(or "makin soap")
Having sexual intercourse; specifically, for a prolonged amount of time. Comes from the fact that when semen gets rubbed up against something it starts to look like foamy soap.
You stick this up your ass to make ass eating more fun since it adds flavor and makes your ass smell nice.
