Basketball players "talking trash"

When you see or hear of basketball players “talking trash” to each other on the court during play, generally, what are they saying?

“I say, your skills at the basket-ball are quite lacking; quite lacking indeed! I imagine I should box you about the ears, Marquis of Queensbury rules, for your impertinence in trying my patience at the game as your better; I shan’t, for fear of your weeping tears wetting my basket-ball finery. Now off with you! Downcourt, knave! Downcourt!”
