DeAndre Jordan -- I've Got the Cure for Bitter Mavericks Fans (VIDEO)

DeAndre Jordan knows it's coming, knows he's gonna catch it -- the absolute WRATH of Dallas Mavericks fans, but last night he could NOT care less ... for one awesome reason.

DJ celebrated his 27th birthday with a bunch of NBA pals at Mastro's Steakhouse in Bev Hills, and on his way out addressed the inevitable -- the Clippers' first game in Dallas and how the fans will treat him.

Watch the video ... 'cause DeAndre's response makes it clear he's soooo FULL of something, and that's dessert.
