Top Definition
A chatastrophe is any typically sudden, disastrous event that occurs during online chat- whether in chat rooms or private messaging.
Room Two was noted as a peaceable room of cozy fellowship chat amongst civilized habitués. After Room One experienced the chatastrophe of a vengeful bot-loading booter, Room One chatters jumped ship and found their way over to Room Two like so many flotsam-borne rats. This sat uneasily upon the regulars of Two, as the Oners were a virtual rogues gallery of the more virulent personality disorders. In their turn, the Room Two chatters regarded the influx of Oners as a chatastrophe.
