LaMelo Ball put some poor kid on a poster Wednesday night ... pointed at him to celebrate -- and then LaVar Ball made an insane claim afterward.
Yeah, SPIRE Academy has officially been BBB'd.
It all went down at Virginia State University in Petersburg, Virginia ... when LaMelo rolled up 30 points, 13 assists, and one monster jam in SPIRE's 91-79 win over Life Christian Academy.
LaMelo's dunk sent a crowd of around 6,000 into a frenzy ... which prompted LaVar to say afterward that Melo's new team is THE BEST ON THE PLANET!
