knotted smile
A vagina. Especially one with twisted and contorted labia minora.
I spent half of high school trying to get a piece of Payton's vagina. It wasn't until prom night that I succeeded. I fortunately found her flat wasted, lying prone on the lawn of the individual having the party. I wasted no time prying those inundated white cotton panties aside to reveal her glistening knotted smile. What happened next is only known by God and me.
