You'd think Lakers star D'Angelo Russell would catch a break at his home court ... instead, he caught a bunch of crap on the way into the Drake concert.
As the 20-year-old walked into Staples Center, a couple of hecklers yelled at him-- "Hide your phone!"
At first, it seemed Russell was going to ignore it -- but moments later, stuck his head back outside the door and yelled something back at the guys.
Our photog says it sounded like he said, "Eat a d**k."
Check out the video ... seems about right.
