In North America, there is a very popular children's game. I'm not sure how far back in time it goes, but it is pretty well known throughout the US and Canada. Whenever two or more people (usually just two) happen to say the exact same thing at the same time, the person who reacts faster puts a "jinx" on the other person by yelling "Jinx!" The only way that the jinx can be broken without penalty is if the "jinxer" (as the person who initiated the jinx is informally known) speaks the name of the person he or she has jinxed. If the jinxed person violates the jinx by speaking first, he or she has to pay a penalty to the jinxer by buying the jinxer a Coke or doing something else that the jinxer requires of him or her. This is a game that I remember very well from my childhood and that I didn't used to think about very much until I joined this forum. Since people from all corners of the world are able to provide some insight into their native cultures on this forum, I thought this would be an interesting question to ask. The fact is, I heard that most world cultures have their own traditions of reacting to two or more people saying the same thing at once (with some exceptions, of course) and that these traditions are typically rooted in religion and superstition. Not only that, but the traditions are very different in terms of form, function, and even age group. For example, the jinxing game is not considered anything more than a fun children's game, whereas in some cultures, the "reaction" is something that is taken seriously across all age groups, and sometimes even only by adults. Also, the jinxing game involves inflicting a malevolent spell on other people and making them do your bidding if they so much as talk out of turn. In other cultures, it is exactly the opposite: a word or phrase intended to ward off evil spirits who might bring bad luck because you said the same thing at once. Sometimes, it might even involve doing something, like touching certain objects. Nothing to do with a game whatsoever. I would like to ask the following: in your country, what is the traditional reaction to when two or more people happen to say the exact same thing at the same time? Is it a children's game or an affair that is taken seriously across all age groups or even only by adults? What exactly does it involve? How does it sound in your language? What does it mean and what is its function? I am not sure whether this is the right section to be asking this question in and I should refer to Cultural Discussions, but I still thought it would be interesting.
