The Fluffernutter. Fluffy cake with nuts, of course. However, I would urge the author to rethink the name. Because, um.
Now, knowing what fluffer can also mean, and knowing that "nutter" is a person who kicks you in the nuts, the name "fluffernutter".... um. A person who fluffs you, then kicks you in the nuts. Then, supposedly, repeats.
Sounds like a weird new S&M fetish.
