TMZ.COM - Kobe Bryant played like a big steaming pile of horse sh*t in his comeback performance last night -- at least that's how he described it in a post-game interview ... and it all went UNCUT on air.

The Mamba let the expletive slip after the Lakers' 106-94 loss to the Raptors ... when a reporter asked if he felt "reborn in a new form" ... and Kobe jokingly replied "right now my form is a horse sh*t form."

Apparently no one was manning the bleep button ... 'cause the expletive went uncut on the live broadcast, and the network promptly apologized for the foul language after the interview.

Kobe finished with 9 points, 8 rebounds, 4 assists, and 2 steals in 28 minutes last night ... but it was his 8 turnovers that had the Mamba fuming after the game.  

The good news: he says the Achilles is responding nicely ... and at least he's still got his sense of humor.
