A medical term; "Anal Shyness" occurs when a person is reluctant to engage in anal sex for fear of hurting or overwhelming their ass. Most commonly found among stubborn females and flaming men who are gay, but haven't engaged in anal sex, due to their anal shyness.

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.
