Jinx também é um jogo infantil , quando 2 pessoas dizer a mesma coisa ao mesmo tempo :
When I was in school, if two people said the same thing at the same time you hurried to say "jinx" first - whoever lost wasn't supposed to talk until someone said their name. A bystander could also say it, and both of the people involved would be caught. I learned from a friend who grew up in another area that "pinch poke you owe me a coke" was the answer to this situation, or sometimes just "jinx you owe me a coke". I saw in an old movie (and another friend said she'd seen it in person) where the two people stopped for a second in their conversation and linked pinkies when this happened, then kept going.
Este jogo prova o quanto Hans e Anna pensam da mesma forma; eles até dizem "Jinx" e "Jinx novamente" juntos.
