butt fluff 

a) Literally: The pubic hairs around the butt. See: buttfluff

b) Figuratively: Style without substance, frivolous, useless, meaningless, unintelligent, pointless, form lacking function, redundant, annoying, irritating.

The Prisoner remake was pure butt fluff. Go watch the original if you have a brain.
