Fb is short for many things I'm sure, but what it is most commonly known and used for is FaceBook.

Facebook is a homepage where one can share photos, status updates about their life etc.

Fb is not something one says while speaking, it is an internet chat or sms abbreviation.

1. (Noun) Fucking Bind Spammer

- Stands for the well-known steam community group, ' Fucking Bind Spammers '.

This group originally created for Killing Floor, the game, is now one of the most-known entertaining communities across the genre.

The most famous way of detecting an FBS (Fucking Bind Spammer), is checking their IQ. If they respond with '~' (Tilde) it means they are a legit FBS.

The Steam community for that originated the FBS: groups/FuckingBindSpammers

It is also commonly known that DOOM is toxic.
You M14+Lar players might have cunt-wiring to re-route your fear of the Fucking Binder Spammers, but We've got nerves of steel.

Stfu, you FBS!

"FUCKING BINDSPAMMERS, I WILL KILL YOU ALL YOU FUCKING SPAMMING, GLITCHING, KILLSTEALING, BODYSHOOTING, PRINTING, BITCHES!!"

A true FBS always knows that Bullpup is superior over a shitty xBow
