I understand that repeatedly lowering your bag to caress a dead players face proves your dominance, superiority and higher skill at sitting in a chair and pressing buttons. You especially prove it when you ride along 10 seconds after a zerg killed that player and do it knowing full well you had nothing to do with that person's death. I prefer /sick then /shovel then /rake but to each his own.
