The noise an A29'er makes when they finally get what's going on. It’s like they just got a free pizza and a gold star.
When my teacher explained the math problem, I said 'Oh!' like I'd been waiting for that all day.
I heard the question and immediately knew the answer. I yelled 'Oh!' so loud the class turned around.
My friend finally understood the joke and screamed 'Oh!' like he had just discovered fire.
