The practice of ingesting a beer per hole on a regulation golf course. 18 beers in 18 holes. It usually results in uncoordinated golf and dismissal from the Golf Course. The destroying of Golf carts, clubs and apparel is also a typical result.
I pulled off 18 in 18 last week and I'm still hung over.
