Slang or jargon for a surfer that uses too single-use plastic. The word is derived from the adjective poly which is used to describe plastic and combined with the preexisting word kook.
Shaun: *uses a straw* *orders a coffee and puts a plastic lid on it*
Clive: Dude, you are such a poly-kook.
Clive: Dude, you are such a poly-kook.
