Japanese habit/custom ~6~ Janken

First of all, I give you an example.
There are three people here. And there is only one cake.
They can't decide who eat the one cake.
How do decide in your culture?
In Japan, we decide it by "janken".
Each person shows weapon  by hand.
I learned that janken is already common in USA and
they call Rock-scissors-paper.

Guu = Rock

Choki = scissors

Paa = paper

In Japan, when we express the three kind of weapon,
usually, the order is Guu, Choki, Paa.

I tell about how to do Janken
1 You say,"Janken Pon!!"
2All of you show your weapon at the same time.
  Guu is superior to Choki. Choki is superior to Paper. Paper is superior to Guu.
3 If the weapon was the same, you must show the weapon again, saying
  Aiko de sho!!
4 You continue until some one win the match.

You can decide the superior person by chance.
So this is the fair and peaceful way when you have to decide who is superior.

If you are excited so much, you may be tempted to show the weapon after
you check which weapon the other person show.
But it is called "Ato dashi janken (Oso dashi janken)"
(=delayed janken)
Japanese avoid from this ato dashi janken whether or not you do intentionally.
If you do that on purpose, you must be blamed by all of the people. ^ ^ ;
