Very simple. You need 2 dice and a jug of a light drink i.e. wine spritzer, beer sandy or a nice punch. Everyone rolls to see who gets to start, the person with the lowest number gets to be the first “Third Man”. Now, the object of the game is NOT to be the “Third Man” cause every time anyone rolls a 3 or a multiple of three the Third mans has to take a drink.
When someone rolls a seven it is regarded as a “social” and everyone has to take a drink. The only way a “Third Man” can remove his title is by rolling a three or a double, he/she is then allowed to nominate any other player as a “Third man”. When someone rolls a double three they are allowed to nominate a second “Third Man”. Until everyone is a “Third Man”. When someone rolls a 1 the direction of play switches. Have fun, and don’t drink and drive, rather party to survive.
