“ Janx Spirit : Janx Spirit is a rather potent alcoholic beverage, and is used heavily in drinking games that are played in the hyperspace ports that serve the madranite mining belts in the star system of Orion Beta. The game is not unlike the Earth game called Indian Wrestling, and is played like this: Two contestants sit at either side of a table, with a glass in front of each of them. Between them would be placed a bottle of Janx Spirit — as immortalized in that ancient Orion mining song :“Oh don’t give me no more of that Old Janx SpiritNo, don’t you give me no more of that Old Janx SpiritFor my head will fly, my tongue will lie, my eyes will fry and I may dieWon’t you pour me one more of that sinful Old Janx Spirit”Each of the two contestants would then concentrate their will on the bottle and attempt to tip it and pour spirit into the glass of his opponent – who would then have to drink it. The bottle would then be refilled. The game would be played again. And again. Once you started to lose you would probably keep losing, because one of the effects of Janx spirit is to depress telepsychic power. As soon as a predetermined quantity had been consumed, the final loser would have to perform a forfeit, which was usually obscenely biological. ”
