Similar to Kitchenheimer's, a portmanteau of 'stairs' and 'Alzheimer's'. Forgetfulness that occurs due to going up or down stairs. The two most common types are:

1. Directional Stairsheimer's. This is when you can't remember if you just walked down the stairs or if you were about to go up.
2. Situational Stairsheimer's. This is when you come down the stairs to get or do something, but forget what that thing is as soon as you get to the bottom. Then you go back up the stairs and immediately remember what it is.
Husband: Why are you going up and down the stairs?
Wife: My Stairsheimer's is acting up. I'm trying to remember what I walked downstairs to do.

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."
