7-14-21
I was first introduced to 7-14-21 at some pongo mess in BAOR during our RAFC visit back in 1969:
Any number of players.
1 set of poker dice.
Throw dice in turn.
Player who throws the 7th ace chooses a drink - it can be as vile as imagination allows. But with that comes a risk...
Player who throws the 14th ace has to pay for the drink (during our BAOR visit, the pongos were gentlemanly enough to charge the cost to 'mess guests' if one of us threw the 14th)
Player who throws the 21st ace has to drink the concoction which the 7th ace thrower chose. Of course that could be the same player, so if he'd chosen something like Guinness, advocat and pernod, then he'd have to drink it!
Throw the 21st 3 times in a row and you'd have to drink the 'loving cup' - consisting of anything everyone else chose.
Later the game was adopted in the ULAS mess at White Waltham, although to keep the cost down, there were set rules. No more than 2 spirits, nothing more than half a pint in total and the only permitted additives were 'recognised' items such as angostura bitters, Lea & Perrins etc. Innocents that we were, we would then go flying the following morning feeling like death.
But we survived....
