someone who you growed up around, and know like family but ain't related to yaz.

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.

A friend who is as close as a cousin.

A person around the way that you grew up with or who is just that person who has your back. They come with a lot of clout because you get to pick this cousin and throw shade on dem real cousins that you aint feelin at the moment. Which probably means you don't want to hear the truth that a real family member will say to you. lol
