The act of eating a Taco Bell taco, then running to the bathroom and defecating in the top tank of the toilet. Then running back to your boyfriend/girlfriend and rubbing your ass on their face.

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.
