plz can u explain me for this

well typically "jinx" is used to describe when a situation is good but then turns bad.

for an example, someone can be like "geez there aren't that many customers! today is my lucky day!" and their coworker can be like "don't jinx it!" and then suddenly a lot of customers come in. that is a jinx ig

for another example if the weathers nice and someone says “i’m glad it’s not raining” and then it starts raining, they jinxed it by saying that

thanks you so much for your explain

great now I feel better
