J-O hand - The hand that you use to get off. It’s the one that’s always

The hand that you use to get off. It’s the one that’s always busy. The other one is just there to be useful sometimes.

My J-O hand is busy. The other one is just there.

I gave my J-O hand all the credit. The other one was just there.

My J-O hand is the one that works. The other one is the one that rests.
