"If you ever see someone running around basteing things, and its not thanksgiving, just run."
When a man and a woman are having anal sex and the man cums inside, after which he removes himself from said anus and inserts a turkey baster inside the anus to retrieve the semen. He then proceeds to put it into the girls mouth.
