A internet conversation/argument that is hilariously one-sided. One person will start off with a bad insult (ex. YER MOM!!!!!1!), and the other will insult him/her cleverly. repeat ad nauseum.

Usually takes place over MSN or another chat tool, where it is saved and sent to peers and associates. Many laughs all around.
