Nickel-head

Thought to be derived from someone who misheard "knucklehead," a nickel-head is someone who's got quite a few screws loose "up there." They aren't the sharpest tools in the shed. Its meaning stems from the fact that a nickel is valued at only five cents, and thus nickel-heads are a step up from their dimwitted cousins, penny-heads.

A homosexual who also has kids. Usually referring to a male. Works in tandem with the phrase “three dollar bill”.
