Making your opponent's moves look like they actually hurt. The unsung art of professional wrestling. Anyone can throw a punch — selling the punch is what makes the audience believe it. Great sellers (Shawn Michaels, Dolph Ziggler, The Rock) make their opponents look like killers. Bad sellers break the illusion and ruin matches. Overselling is its own art form — see: HBK vs. Hogan, SummerSlam 2005.
