A cheesy, foul-smelling paste produced by a chronically unwashed vagina. Frequently, it will collect around the vulva where it waits to ambush the unsuspecting when panties are removed in anticipation of (usually oral)intercourse. Twat junk is commonly associated with various infections of the cunt and invariably forms pasty little pellets that may adhere to the labia or collect in the undergarments.
I hope Neil used a gasmask when he went down on Darlene. That girl's twat junk is just plain noxious!
