1. Overgrown Jewish man. A donkalouch can typically be identified by one or a combination of the following characteristics: awkward dance movements, attracts swamp girls no better than a 6, hits golf balls backwards, easily confused with Godzilla, bald, pale complexion, always 'forgets their wallet'.
