hai ngoc la
A weird way to say yes in Japan. It’s like when you're too lazy to say 'yes' but still want to be polite.
My friend said 'hai ngoc la' in Japan and the whole class laughed at him.
I tried to say 'hai ngoc la' in a restaurant and the waiter gave me a weird look.
My teacher said 'hai ngoc la' during a test and I thought she was confused.
