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.
"My visit home turned into Bisexual Groundhog Day. My mom acted shocked when I told her I'm going to Pride next week, so I had to come out to her as bisexual AGAIN."
