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.
Example 1: "I came home and my dog had shit all over his kennel. His fur was covered with shit and the whole house smelled like shit. It was a total shitastrophe."
Example 2: "My dog shit on my floor and the roomba dragged it all over my house. It was a shitastrophe."
A scamtastrophe is a catastrophe that is caused by an absurd amount of scamming in a society or community that causes the economy to fail, and the community to collapse in utter destruction.
The act of an outbreak of scammers on an online game, such as Roblox, that causes the platform/game to shut down either permanently or temporarily in a sense of a scamtastrophe.
