Lonzo Ball OBLITERATES UCLA Engineer Student In Dunk-Off

This is amazing ...

UCLA superstar Lonzo Ball accepted a dunk-off challenge from a fellow Bruin student ... and it ended with a KILL SHOT!!

It's great video -- non-collegiate athlete Kevin Wei (who's studying for his degree in Applied Mathematics/Computer Science) went to Pauley Pavilion for the 1-on-1 dunk-off.

Wei actually managed to DUNK ON BALL (yeah, it's a lowered rim but still!) -- and that's when Ball decided to exact some hardcore revenge with a windmill powerdunk.

R.I.P. Kevin Wei.

(But really ... props on the insanely cool video).
