NBA Star to Meek Mill -- I'll Write You a Check ... But Please, Stop.

Detroit Pistons point guard Brandon Jennings thinks Meek Mill's comeback diss track to Drake was so bad ... he wants to pay the guy $150 to just stop.

Mill finally dropped, "Wanna Know" last night ... which was universally panned by everyone from rappers to politicians ... even a burger joint took a shot at Meek.

And Jennings was critical as well ... check out the screen grab our friends at BSO captured moments after Mill dropped the track -- it's pretty harsh.

By the way, there's backstory -- last week, Meek dissed Jennings for taking Drake's side in the rap feud.
