The authority of all bros. Although this person is "the authority" he is still super chill and usually welcomes worthy outsiders into his circle of bros. This term was introduced in the south park episode "Broadway Bro Down," which originally aired 10/26/11. The term was used by randy marsh participating in a bro fight with Stephen Schwartz who then replies saying that his famous musicals clearly make him the brothority.

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.
