Stickum = selfish ... so says Charles Barkley who says Dwight Howard needs to ditch to the sticky stuff 'cause it screws up the ball for everyone else on the court.
Barkley was out in NYC Tuesday when he told us the stickum isn't that big of a deal -- but Dwight shouldn't be using it.
"You can't use stickum, 'cause you screw it up for everybody else," Barkley said ... "Other guys need the ball too!"
The NBA issued an official warning to Howard after he was busted using the substance against the Hawks -- Howard says he doesn't think it's a big deal.
