Jinx California

Typically, 2 or more people will say the same word, phrase, sentence, etc. and then proceed to say "jinx" and count from 1 to 10. To save time, you can say "jinx california" because they already have 10 letters. The rules in regular jinx still apply here. Just that you can add "california" to the end of jinx to beat the person you've said the same word, phrase, sentence, etc. with.

"Shut up."
"Shut up."

"Jinx California! (skip counting 1 to 10 out loud)"
