A cyddie is someone who will always take the brunt of the jokes. She will always firm the jokes and cry secretly in the corner until she builds up enough courage to come outside and take the force of the next joke. Usually about 5 jokes in she will reach her limit and tell them to fuck off and never talk to them again. She is the type of person who will shit under your pillow and not tell you.

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.
