Fuck My Chat - When you are on facebook chat, and suddenly either your conversation is gone or the chat application disappears to the bottom of the screen. Pretty much the shittiest thing that will ever happen on facebook because then you need to say "sorry, what did you say?" or log out then in again.
You'll know when you see it. It's absolutely horrible.
