"You like that you fookin gobshite?!?"

When the man, wearing a Larry Bird jersey, is about to nut he backs off behind the three point line. This allows the woman, wearing a Paul Pierce jersey, to gather her explosive diarrhea. He then nuts on a nerf basketball, shoots the three in her ass, and she rejects the shot at the rim... obviously.
