chat dumped

Getting dumped by someone that you're having a chat affair with. Only counts as a chat dump if the chat's been going on for more than one exchange. Chat dumps can be "spoken" ("I don't want to chat with you anymore"), harsh ("fuck off"), or dickish (disappear from IM).

Person 1: Shit, I think I've been chat dumped by this really hot guy dood.
Person 2: What happened bro?
Person: Guy just stopped chatting suddenly. Fuckin' asshole. Bad chatiquette.
