Nutter Flutter 

A delicious snack in which a jar of marshmallow spread (usually bought from the local safeway) and peanut butter are smeared graciously between either 1)Two waffles or 2) Two pieces of bread.

John: Hey dude what do you have to eat around here?
Frank: Dude I'll make some Nutter Flutters
John: Fuck yeah man, I love those things!

Flutter Nutter 

The act of taking peanut butter and smearing it in your partner's ass during sexual intercourse. The proceeding to anal your partner until you cum in their ass. Making it look like the delicious snack called a Nutter Flutter or Flutter Nutter.
Butt cheeks= buns, peanut butter = peanut butter, and the cum = the marsh mellow paste

So I heard Anthony gave Kamii a Flutter Nutter last night, is that true?

I cant wait to make you a Flutter Nutter in bed.
