Steve Austin isn't taking too kindly to Goldberg's suggestion that his famous beer chug wrestling celebration was a sham -- telling TMZ Sports straight up, "[Goldberg] is full of s**t."
Goldberg seemed pretty serious when he called shenanigans on Austin last week -- telling us he's 100% certain Stone Cold wouldn't really consume the brew.
But Austin says that's a load of horse crap -- mostly.
Steve admits he didn't drink ALL of the beer ... but he took down about 50% of every can -- and he's got a pretty good explanation.
Long story short ... Austin says Goldberg is his boy, but they're gonna have some words.
