That's a great question, so most people got (and still do) made fun of bc of it but it's basically where you create a character to hang out in your favorite show/book/etc and sometimes you write/draw a character that is shipped with a character you like. Tldr it's basically fanfic 😆

I mean, yeah what do you expect, if people are going to curate their own online experience, you're bound to be on someone's list (I probably am LOL) .
