Desperasexual

Bennie was a friend of Rat. According to Rat, Bennie is attracted to both men and women, in which Goat replies that this would make Bennie bisexual, but Rat then says that it's not exactly true, as Bennie doesn't choose to be attracted to both genders and that he only does it because he's lonely and will take what ever he can get, which is called Desperasexuality.
