Ice Cube -- I 'Was Robbed' Comment Wasn't a Diss to Paul Walker

Ice Cube is setting the record straight ... saying he was not taking a huge shot at Paul Walker when he griped about losing to him at the MTV Movie Awards -- and claims his words were misinterpreted.

Cube raised eyebrows when, according to USA Today, he said ... "We was robbed" in the Best Onscreen Duo category. He and Kevin Hart's "Ride Along" lost to Paul Walker and Vin Diesel's "Fast & Furious 6."

He added, "We had the best chemistry of everybody nominated, for us not to win was crazy."

Sounds like Cube was getting some heat ... because he's now saying, "I wasn't really mad we didn't win. So I would never diss the actors who won. Not even Paul Walker."

Ice Cube also tweeted, "Ice Cube is not a sore loser. I was born losing. This winning s*** is what I gotta get use to."

Sources close to the actor/rapper tell us he had a joking tone during the USA Today interview ... and was just busting on award shows since he doesn't take them seriously.

We feel you on that, Cube.
