A type of marshmallow cream that people in New England eat. Commonly eaten with peanut butter on a sandwich as an alternative to jellies and jams or honey. Kids get a sugar rush on it and often end up driving their parents bonkers afterward and getting in trouble in school. Doesn't have to be refrigerated.
Junior, you want peanut butter and fluff for dinner, or mac 'n' cheese, or clam chowda?
