1) verb - To unintentionally curse someone or something by talking out loud about bad things that could potentially happen in the near future.
(Similar to the Knock on Wood superstition)

2) noun, exclamation - A game where two people try to be the first to shout "Jinx!" immediately after both people accidentally say the same word at the exact same time in a conversation. The person who says "jinx" first wins, and the loser is either branded unlucky until they win another round in the future, or in some cases, is expected to buy the winner a can or bottle of Coca-Cola.
1) Pete: "That engine does not sound right. I hope it doesn't blow up on you while you're driving."
Doug: "Come on, don't jinx it!"

2) Alice: "What's the word for it? Indo...indie..."
Both at once "Indigenous!"
Mary: "Jinx! Buy me a coke!"
Alice: "Damn it. Who even came up with the coke rule anyway?"

Jinx is a term used by the weak minded who create a self fulfilling prophecy for their own downfall.
Person A: "I can't tell you my plans I don't want to jinx it."

Person B: "All that means is that you have no real faith in your plans and are going to fail."
