A nonsensical and inoffensive term used to describe people being annoying or stupid. Screwdaddy has no origin other than the fact that is the perfect sounding word to express someone's annoyance.
A miscellaneous piece of hardware that requires some sort of screw driving implement (be it a Phillips head, IKEA wrench or otherwise) to put it in its place. The term is a hybridization of screw and doodad.
Has anyone seen that screwdad we use to keep this amplifier bolted down to the rack?
