Koudo

It's the most dangerous curse word you can use. It means all these words together, bitch, fuck you, idiot, stfu, stupid, whore, hoe, clown, show off, teacher’s pet, creepy, dumb, ginger, prick, bastard, arse, ass, balls, cunt, shit, dickhead, cocksucker, burden, problem child, snitch etc. Just all the bad word you know. Use this word wisely, this is more than just a word you know. They don't need to be all of them before you can call them "koudo", but they need to be at least two of those things.

Max: "Emily told the teacher where i were, because the teacher would give extra points to the person telling her where i were."
Lilly: "She is the teacher's pet and a snitch, what did you expect?"
Max: "You're right! She is also a bitch!!"
Lilly: "You know what she is a koudo. She deserves to get called koudo!"
