A sex move, similar to a spit roast. In a threesome involving two men and one woman (or three men, I don'
t judge), one
man fucks the woman doggystyle while she gives the other
man a blowjob. Upon nutting, the
man behind her cums in the vagina (fluffing her up), while the other man nuts on her face.
The name comes from the delicious sandwich made with peanut butter and Marshmallow cream.
