Twass

That area of skin which lies between the "twat" (vulva) and "ass" (anus) on a female's gentalia; Also known as the "taint" or "choad" for females; "tweener" for both males and females; and "painus" for males.

If you wanna' make sure she's enjoying your oral escapades below her belt reach beyond variety and repetition and frequent the perimeters--especially her clit and twass.

When you wear lace panties,and the sweat and goo from both ass and twat leak thru the lace, making a thin pancake like waffle inside your pants

That guy is a twass waffle
