Jagshemash! ... bad news for Borat -- you might get your face bashed in by one of the baddest men on the planet -- a boxer from Kazakhstan who's got a serious ax to grind over the 2006 flick.
The man with the beef if Gennady Golovkin -- Triple G -- who's KO'd the last 20 fighters he's faced.
Gennady was out in L.A. for the ESPYs this week --so we had to ask how he felt about Sacha Baron Cohen's portrayal of his homeland in the movie that made more than $260 MILLION worldwide.
Bottom line -- he wasn't happy about it ... calling it "not funny," "stupid" and "dumb."
High five!!!! (Or not).
