An italian expression mixing "caga" or "caca" that means pooping, and "sburra" or "sborra" that means cum(or "cuming".
It is used as a nonsensical expression to let people almost get the meaning of it, but then no, it is a wtf word that will shock your italian friend for the beautifulness of the juxtaposition of those two words.
"Va bene Ciro, dormi pure."
Ciro: "Ho fatto, ho fatto la cagasburra"
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.
