Ja-chang
A rich Asian person who's too proud to admit they can't say cha-chang. They act like it's a personal insult.
He yelled at the waiter because he said 'cha-chang' instead of 'chah-chuhng.'
My uncle threw a fit because the restaurant didn't say it the way he wanted.
She walked out of the restaurant because they didn't say cha-chang right.
