Ghetto Jousting, a euphemism for "drive by shooting". A man drives in his car, and approaches his rival. He rolls down the window, if he shoots his target, kills him, and drives away, he wins the joust. If the target were to survive, he must drive to his target, roll down his window, and shoot him, whoever kills his target first, wins the joust.
Marty did some Ghetto Jousting against Tyrone.
