Dillon Brooks continues to catch strays after his trash talk blew up in his face this season ... 'cause the NBA hooper is now a punchline in Polo G's new freestyle -- and it's harsh!!
The Chicago artist dropped the vicious bar while appearing on "Justin Credible's Freestyles" with Power 106 in L.A. ... where he flowed over Ja Rule's classic "New York" beat.
It only took a few seconds for Polo to name-drop the former(?) Memphis Grizzlies player .
