Among other feats, in the 1976 ABA All Star Game during the first slam dunk contest Dr. J dunked the ball after leaping from the free throw line.
When driving towards the goal, Dr. J would often jump parallel with the baseline. While in the air, he would reach around and jam the ball into the rim from behind the backboard. His method of entry from the rear became his signature move, which resulted in him receiving much attention from women, which resulted in Dr. J (allegedly) entering said women from the rear. They loved it.
Guy 2: He had anal sex with a woman last night. He jammed it in from behind like Dr. J. Straight up Dr. J'ed her. The Dr. J jersey is like the scarlet letter, only the opposite.
