Khe Sheen is a funny person you’ll meet. Almost everything they say is sarcastic and they make many jokes! Though they are insensitive when making jokes about people, you will become friends with them instantly once you are able to adopt their joke-ish personality and understand that they don’t mean what they say. While they can be a bitch sometimes, they are still fun to be with!
Be a Khe Sheen and cheer your friends up!
