I'll be honest, I had no idea who PBA bowler Sean Rash was before coming across this video but clearly he is a master of the art of calling out an opponent.
During the Geico PBA Shootout in Chicago, Rash decided after bowling a strike to verbally call out opponent Jason Belmonte and his choice of water receptacle.
