Sometimes prounced "jibba-jabba". Although it is only a made up word (made by African American, mohwak sporting, gold chain wearing, wrestling superstar, Mr. T), it is sometimes used today by weird school kids. Copy off of Mr. T too much however, and he will throw you.
Shut yo' jibba jabba or I'm gonna throw you, foo'.
