When a man or woman wears a strap-on dildo on their head and then uses it to pleasure their female partner by nodding their head up and down and grunting as if they were in fact an angry rhino.

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.

When a girl is giving oral to you, you pull your cock out, and cum in her nose, then get her to snort it out onto your face. Like steam coming out of an angry rhino's snout.

When receiving fellatio, just before the finish, pull back and blow up up the person's nostril.
