Snoop -- Destroys Steelers Kicker ... FIRE HIS ASS!!!

Snoop Dogg is PISSED -- calling for his beloved Pittsburgh Steelers to FIRE THE HELL out of kicker Josh Scobee ... after he blew TWO huge kicks last night that essentially cost Pittsburgh the game.

Scobee had TWO chances to tack onto Pittsburgh's lead in the 4th quarter Thursday night ... a 49 yarder and a 41 yarder ... but he choked both times ... giving life to a Baltimore comeback.

The Steelers eventually lost the game in overtime ... and Snoop thinks Scobee should pay with his job.
