Jinx
A jinx is a curse of bad luck. Players say a person or an action jinxes a result when they believe it brings misfortune.
The simple explanation
If a player says 'I never lose here' and then loses, someone may say that he jinxed himself. It is a superstitious word.
A closer look
Poker is a game with a lot of variance, so players often find causes for streaks. Jinxes, lucky seats and lucky charms are common, but they do not change the cards. The best response is to stay calm: do not change a correct decision because of a superstition. See also Jonah.
A practical example
A player says aloud that he cannot lose a pot with aces, then loses to a flush draw. His friend says that he jinxed himself.
