How'd J.R. Smith celebrate Joe Biden's victory?
He drove around bumping "F*** Donald Trump" and flipping off MAGA supporters.
So yeah, just as you'd expect ...
The L.A. Lakers star hit the streets (of what appear to be Beverly Hills) on Sunday -- where he blasted the YG song from his BMW, while leaning out of his window and shooting the bird at all of the pro-Trump protesters he saw.
Smith loved every second of it -- and was smiling and laughing while trolling Team MAGA.
Of course, Smith is the latest in a long line of NBA players relishing Biden's victory .
