Very similar to a SlurpyDogPussy except the pussy has taken on characteristics that now show signs of being shot out burnt out and completely worn out. SlurpyHorsePussy is the next evolution after SlurpyDogPussy in the subhumanspecies sex bestiality realm as once Dog Dick doesn't work for that DoggyPussy any longer than a woman graduates to Horse cock and once horse cock gets ahold of that pussy it takes on a completely new and different completely worn out look and it's all bad and downhill from there.

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.
