praeternatural knack for alienating half of the group of people one is with when seated at a sporting event or concert; analogous to cock-blocking other would-be participants in a conversation. Etymology: In 1996, during a St. Louis Cardinals game at Old Busch Stadium, one of the descendants of the Busch family turned 90 degrees, thus shielding four of his fellow Cardinals fans from the conversation among a group of nine. Then, he reversed field, and alienated the other four before alternating sides and frustrating fans of all ages well into extra innings.
Tommy was thrilled with his seats at the Coldplay concert until after the opening act, when Greg turned to talk to Joel and then gave Tommy the Buschman Blockout for the rest of the show.
