look up any word, like blumpkin:
 
1.
A straight single woman who consistently hangs around a homosexual man so that others won't think he is a homosexual.
The only reason why Tommy invited Shelly to his parent's Christmas party was because he didn't want his family to know that he was gay. He had no real romantic interest with her and her only function at the party was to serve as a fagpin so his parents wouldn't discover his true nature.
