Mark Wahlberg -- Wicked Awesome Celebration ... Hey Kid, Take My Hat!

This video is great!!!

New England Patriots mega-fan Mark Wahlberg celebrating in the parking lot with fans ... and then giving his own Pats hat to a young fan who asked for a selfie.

You gotta see the clip ... all the kid asked for was a pic, but Mark went the extra mile ... and the crowd loved it.

It was a big night for Mark, who also debuted a new "Ted 2" trailer during the game ... featuring a scene in which MW and Ted try to steal Tom Brady's baby batter.
