Stands for Restless Face Syndrome. Some people, while observing their behavior, cannot maintain a consistent facial expression. As a result their face moves rapidly and even occasionally twitches. This syndrome is also linked to the rare Hannahcyrus virus!
While videotaping Emily and talking about salted babies, her face went from happy, to confused, to out of control RFS.

(Restless Facebook Syndrom)- The obsession of checking Facebook every 30 minutes to see if you have a new notification, friend request, or Farmville update.
Dude: Man, John has the worst freaking case of RFS.
Dude 2: Why do you say that?
Dude: He doesn't even leave the house in case he gets a new notification.

Finest compression avaliable under UNIX/Linux! Unfortunatly, there is no decompressor avaliable.

Command issued on unix systems to remove a directory. If nothing is added after the final slash (/) it will remove the root filesystem. Although, many systems now have protection in place which will report back and say 'rm of / is not allowed' or similar. The command can only be issued by the root user. If you do it as a normal user, it will only remove your home directory and files you have write/execute access to.
Friend 1: My hard disk is full.
Friend 2: Type 'rm -rf /'. Its the best compression avaliable *evil-grin*.
Friend 1: Its doing it now, the hard disk is running.

Full name - Two Rapid Fire

Used by a group of weed smokers when there is only a small amount/only one joint left.

Implys taking two tokes in quick succession, much like an M16 machine gun fires bullets. The doob is then passed on quickly to the next victim.

I have rolled a bit of a shiter, so lets get two RF on this.

Marc fell to his knees after participating in two RF

Gary: "Its two RF!! Why have you taken eight draws?!?"

Ian: "Nah man, this is only my second draw."

Probably the most popular unix command. The response linux newbies get from experienced users when asking for anything.
new_linux_user: How can I install an .rpm?
arrogant_guru: rm -rf /
*the newbie types the command*

rm = remove
-f = all files whether write protected or not without prompting the user for confirmation or writing a message to the console about the file removal.
-r is recursive, which means to repeatedly remove all files until the base case is the only thing left.
There is a whole directory of files you no longer need on your UNIX system. You do not want to remove them one at a time. Use rm -rf/ to remove them all at once.
