Chatwipe

What happens when you're chatting on a social networking site's (Facebook) IM when all of a sudden your conversation randomly erases permanently, therefore causing you to miss something that was said.

(Facebook chat window)

Me: Dude, I can't believe she still has that up!! (link to embarrassing picture)

Mikel: Dude, no way!!! ROFL

*chatwipe* (causing me to miss his message)

Me: Ummm... can you repeat that, man???
