A bro that is always at a party but never seems to get in on drinking games or other party activities. He can be seen casually sipping at his beer whilst chilling from a distance or adding the occasional chuckle and/or witty comment. They are very rarely seen alone, usually in groups of 2 or 3 so as to seem like they are having fun. Can also be abbreviated to BGB.

The phenomenon of having to come out as bisexual to the same person/people repeatedly because they assumed or hoped that your sexuality was a "phase." Refers less to the holiday and more to the 1993 Bill Murray comedy film in which the main character experiences the same day over and over.
