Drink Club
A concept not far removed from that in the movie "Fight Club". This particular concept is borne from the inability of a collection of adult males to organise a night-out. A "night-out" having roughly several billion alternative meanings (just not that one - you down the back there! Tut-tut). So this term "Drink Club" infers a measured and proactive approach to quell that issue of inability to organise.
The first rule is: There is no Drink Club.
Really.
Really.
