Apply a healthy layer of your favorite peanut butter to the inside of your partners asshole, then have vigorous anal sex until they prolapse. Upon prolapse, pull out and enjoy the warm gooey Siberian treat.
My girlfriend came back from a BDSM convention and told me about the Peanut Butter Gulag; it was great until I learned that I was allergic to peanut butter.
A burger with peanut butter on it that can be eaten or used to describe the way female genitalia may look or feel after a long, rigorous night of intercourse.
"How did it go last night?"
"Man we banged all night long! I had her lookin' like a peanut butter burger down there!"
When you lube up your asshole with peanut butter (chunky if preferred) and a dick or dildo with unspecified jam or jelly and fuck the asshole and then suck mixture the dick or dildo.
