Definition

A delightfully obscure insult for someone lacking basic common sense or intelligence. It suggests the person is so clueless they might as well be standing downwind of a nuclear test site. This regional gem is perfect for when 'idiot' feels too mainstream.

Example Usage

That downwinder brought a surfboard to a ski resort and wondered why people were laughing.
