I have some lingos that have popped up since December or were never mentioned:
idfc=I don't fucking care.
idfk=I don't fucking know.
/rules=A command you type which shows the server rules, which you have agreed to by playing on WoS.
SW=Stunt-War.
f/ail(or anything with a slash after the first letter) What Nka19 says to vlParadoXlv to annoy him about his "command failing problem"
Noob=Can mean what Stumpy said, but some players of WoS define it as someone extremely annoying.
Fat=Nka19
Trial Noob=Level 1 Administrator.
Brosch=Brendon's first World of Stunting username, still used by Kubson.
Mesa=Me and Amanda call it "the Jeep."
That's about it.
