yankeeshater 

1. One who derives great pleasure in the failings of the New York Yankees and feels sickened by their successes; (2) the opposite of one who roots for the New York Yankees.

In Boston, almost everyone is a Red Sox fan and a Yankeeshater.

yankeeshater 

One who believes that Jeter Swallows, one who will never give up on the Red Sox, one who holds nothing but hatred towards the New York Yankees.

If you are a Boston Red Sox fan, you are a yankeeshater.
