A large group of nerds of either one or multiple kinds, who are mutually friends. Like any gang, except that all members know calculus, have an opinion on the economy, philosophy, and will try to convert you to their OS/Browser/Console. And are less likely to be able to take you in a fight.
Sometimes acting as a guild with a monopoly on intellect, and other times as an average bunch of friends.

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.

May be spotted in a nerd bird or library.
