When your friend or roommate is laying the pipe and it sounds more like a hamster furiously spinning its wheel than a trip to slamsterdam.

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.

The act of shooting a live hamster, ( without harming it) into the anus of your partner with a homemade potato gun. For just plain fun, or for slightly abnormal sexual desires.
