A douchebag of such magnitude that it could cleanse a whale's vagina. From Ron Burgandy's made up definition of San Diego as German for "a whale's vagina."
During intercourse, you stick your index finger in your butthole, and then stick in your partners butthole and then you shove it into your partners mouth.
