Jinx! Blackout! You owe me a soda!

When you say the same thing at the same time as someone else, you can say jinx. If you say jinx first the other person can’t talk unless you say their name 3 times. Sometimes, they can talk, they just owe you something. So this phrase came along. I’m not sure we’re the blackout part came from. So when you say jinx first, instead of making someone silent, you can say Jinx! Blackout! You owe me a soda! And yeah, they owe you a soda. Sometimes people will say a variant of this where they say Jinx! You owe me a Coke!
