Koi is a fish and a stupid one. He has lavish hair and he is dumb. This is true. This started over him arguing over every pity thing. Wow he is stupid.

Koy is as close as you're going to get to a "slur" for a group of people that aren't discriminated against. I'm talking of course, about GINGERS. When your ginger friends are pissing you off, call them a fucking "Koy". Koy is based on the word "Koi" which refers to the domesticated amur carp, typically a bright orange in color.
Person 1: "Look at that fucking koy. Ugly bastard."
Person 2: "Wow. You really hate gingers!"
Person 1: "A ginger killed my entire family."
