Redefined by the youths of Beverley, East Yorkshire and the surrounding area, oust is a general exclamation that can be used in a variety of circumstances. It can be used as an expression of greeting, or as an insult. It can also be accompanied by a click of the fingers, followed by pointing at the target of the word. People who are ousted in this way are generally geeks with no friends, as they are an easy target for abuse.
