When a woman is on her period and doesn't do a good enough job wiping after taking a shit, blood and crap are stuck in the butt crack and are therefore called a peanut butter jelly sandwich.
My girlfriend Teresa is so gross. She never washed away that nasty peanut butter jelly sandwich forming in her ass crack.

The result of an feceal infected pussy from fucking "bi" sexual men, dickheads that don't wash or shitskins.
In Africa they probably have so many diseases from the idiot shitskins making to many peanut butter jelly sandwiches with the dumb bitches.
