On heavier girls, it is the protruding roll of fat just above the vagina. Also known as a "gunt".
You can really see your mom's cunt cakes in those stretch pants.
When you bake a cake in the shape of a semi circle and cut out part of the middle, fill it with icing and put a tube of icing in a shape of a ripple like thingy so it looks like a ravashed bagina. put black licorish (no fucking clue how to spell it) and arrange over cake like pubes. Put cherries and cherrie juice in the opening and have a white buldge in the middle for the enourmous clit. Have sexless friend throw face first into cake to eat it out.
