Joehead

A term of ridicule assigned to a young child with a disproportionately head/body ratio.

Typically used as an insult of last resort (when the user has exhausted all logical alternatives and must resort to aesthetics-based attacks).

Extremely powerful - but with long lasting effects that will cause the recipient to hate you deeply for life.

I thought Joehead was about to kick the game winning goal, but instead he capsized under the weight of his own head at the moment he was about to kick for a score.
