The act of parting the flange and enjoying the pink pleasures of a slightly questionable member of the female species that one may find in a place like Swindon on a Saturday evening.

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.
