Facebook Instant Messenger. A process where two (or more) persons have an absurd conversation using some other unlucky person's Facebook
wall. This process gives the victim hundreds of notifications
, a giant-ass conversation on their wall and is a great way to pass the time online. Common procedure includes signing in (ex. iliketitties42 has entered chat), using away messages in response to any other post (auto response from iliketitties42: i am currently taking a shit
) and signing off (iliketitties42 has left chat). A great prank to pull on uptight people or people who take their lives too seriously.
