Cemex would be a term similar to jinx, except you don't put bad luck on the other.
In most cases, you say "Cemex" when the other person says what you were just thinking about.

The name came when intelectual south slavic youngsters were on a bus and one of them was questioning:
1: if it's jinx when two people say the same thing at the same time, what is it when two people think of the same thing at the same time?
2:*profoundly looks out the window and stares at one spot until a bag of cement flies in the view* *turns around* it's called cemex.....
1: That guy over there has nice hair
2: he looks like Jack
1: YES CEMEX

1: I'd love some cheap Konzum chocolate now
2: aha, cemex

1: dude the craft store is open and they're selling custom flags
2: custom flags.... OH

1: IS IT CEMEX
2: I THINK SO
