The phrase became famous when Dallas Cowboys coach Jimmy Johnson shouted it in the locker room after Dallas beat San Francisco in the 1993 NFC Championship Game. The clip captured the team's confidence on its way to a Super Bowl win, and fans quickly adopted it as a rallying cry. It has since lived on through sports broadcasts, crowd cheering, highlight reels and social media, where Cowboys supporters revive it after every big victory and rivals reuse it ironically after Dallas loses.
