(n) A hand-job where peanut butter is used as a lubricant. When the male ejaculates, the semen (aka "marshmallow fluff") is then mixed with the peanut butter, reminiscent of a fluffernutter sandwich.
I didn't know what she had in mind when she brought out the peanut butter, but then she showed me the "fluffernutter."

A fluffernutter is a guy who blows their load when being fluffed before actually having intercourse. This word would usually be used as a negative nickname for someone spraying their warm gooey load all over a poor fluffer unexpectedly.
I was at a party with Kyle last night and this one chick kept fluffing us before we would bang her friends. He kept blowing his load on her before he could join the big game, what a fluffernutter.
