Gaming superstar Bugha -- who just won $3 MILLION in the Fortnite World Cup -- was "swatted" during a Twitch stream on Saturday ... after someone pretending to be Bugha called police and claimed he killed his father.
The 16-year-old -- real name Kyle Giersdorf -- was playing the same game that made him an instant millionaire when armed cops surrounded his home.
"I've been swatted," Bugha said on the livestream ... which, BTW, is a dumb trend when someone makes a fake claim on a 911 call to get law enforcement to crash an unsuspecting victim's home.
