6:30 AM PT -- 01/03 -- AB didn't bolt off to the airport after his infamous exit from Sunday's game -- instead, he hit up a celebrity driver to come get him ... and the NFLer was clearly in a great mood.
The driver -- Danny Chalet -- posted videos to his Instagram account ... showing AB grinning from ear-to-ear and talking on the phone after getting picked up.
But, it appears that AB was in no rush to leave town ... with Danny hinting at AB staying in the area to party.
As for any sort of official statement from Brown, the receiver posted a short message on Instagram ... saying, "Big MAD (Making A Difference). Thanks for the opportunity"
2:54 PM PT -- AB was spotted outside MetLife Stadium shortly after his exit ... wearing the same clothes he wore when arriving to the game, and his luggage by his side.
It appears he's waiting for a car service to pick him up and presumably take him to the airport ... considering there was no way the team was gonna let him fly home on the Bucs' plane.
Mike Evans appeared to try calming Brown down, but his efforts were unsuccessful ... as AB stripped down to just his pants and cleats and waved to the fans as he trotted through the end zone and off the field.
As it turns out, MetLife Stadium security reportedly thought AB was a streaker at first ... and initially tried to stop him before realizing he was a player.
AB had 3 catches for 26 yards before leaving the game.
