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.
Definition 2:
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.
