OC 

An OC (original character) is a character that is made by someone. Most times when people make an OC, it's from a game, but it can also be about other things. Sometimes an OC is something called a Mary Sue, but thats another story for another time. Usually, an OC is put into fanfictions, which most times, they are the main character. I wouldn't really recommended reading the fanfictions, because sometimes they.... Well, let's say, sometimes they aren't for all ages (if you know what I mean ( ͡° ͜ʖ ͡°) )

Lilly : I don't really care about OCs, because I'm an UnderTale OC.
Me : Lilly! You aren't supposed to know that!!
Lilly : the worst part about being an OC is most of them don't know they aren't actually very original.
Me : yea... Some are literally fucking recolors

3. Rich white kids who are rasicst and mean. People can't accept an opinion and make fun of cool kids or people who are not "tan" or "surf". People wear a lot of Roxy even though they do not surf. Rap is mostly listened too her. People in Orange County do not know good music.

"You're a sad and deprived child...I could go around and scare lil kids with your face!" (comment directed at me for being cool.)
