Jarateed or "Jarate" is a synonym for "Pissed off" or "
Piss".
It was derived from Valve's
game "Team Fortress 2" in which the character,
Sniper, uses a mason jar full of urine. The in-game name for it is "Jarate" and upon throwing said jar the character will yell "Jaaarate!"
Jarateed is also a word replacement for "pissed" on the Steam User Forums. The word filter will replace "Pissed" with "Jarateed". Clever reference on Valve'
s part.
