A crusty residue left in the crotch of a womans panties. Sometimes white, yet sometime with a redish tint. The color of the stain is determined by whether or not the female has entered her monthly bitch syndrome. If it tastes like chicken it is okay to keep on lickin, yet if it tatses like trout get the fuck out. Also used to define an overbearing female, or even a douche bag male.
I was about to lay the hammer when I realized that cunt stain Ashley had a cunt stain on her thong.
