To stick a cork up a seagull's ass, and wait for him to crap it out and feed it to your girlfriend.
EX.1 "I was on the beach with my girlfriend, when I grabbed a seagull and decided to give my girlfriend a korcull.

EX.2 "My girlfriend wasn't too in to the idea of a korcull, but she was in the mood so I told her if she did that, it would turn me on."
