Explaining the rules

Playing a game at a bar with Austin. It’s a drinking game and a little complex, with a judge and elimination-style mechanic. I remember there was a metal fence and it was very involved. I get confused by the mechanics but slowly understand as I try to explain it to Austin, who clearly understands it already. Austin is with a friend, and as he leaves our table I rush up to the bar to buy his next round. But he is gone when I get up and already back to the table.
