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.

Acronym: Foot In Mouth Syndrome

Refers to the disorder which manifests itself when you inappropriately make a statement at an inopportune moment, often deemed irrecoverable - thus you have inserted your foot into your mouth.

Typically followed with embarassment & many apologies, or a tacit understanding about your position.

Derived from the abbreviation FM, meaning Full Metal, Fim is a capture the flag player in JKA/JK3. Seated among the top North American players, Fim is often associated with the term "emo" due to his tendency to attempt to lower people's expectations of him by convincing them he sucks. Nobody knows why Fim does this with certainty especially considering that it almost never works due to Fim being one of the fastest players of the game. When confronted with this fact, he almost always responds with the same statement declaring that while his speed is substantial, he lacks any form of aim and can only be considered a good offense player at best. This, however, is also untrue as Fim is one of the best Base Defense players, a position that can, at times, require significant ability aiming.
JaXHaX: Fim r u playin?

JaXHaX: wtf you faggot...come or spec..u choose
