methanical pancake swiveller 

A man with long, greasy hair, green teeth, baggy pinstripe trousers with braces and white plimmies. He sneaks around on farmland waiting for a cow to drop a pat. Slavering with excitement he drops his pants and swivels his bare arse on the still-warm bovine pancake whilst making high-pitched mooing sounds.

Its amazing how many methanical pancake swivellers you see on a sunny day.
