Chattin shit is usually a hereditory desease that is often brought on by the
chatters own descretion. If this is a common thing, then it is known as a
chattin disorder. A chattin signal with the hand can also be delivered at the same time. "Self chat" occurs when a person chats shit about themselves, usually purposely.
