ladylike
A girl who thinks she's the best and doesn't care if people laugh at her.
She said, 'You're not even good enough to be my friend.' Then she walked away and tripped on the stairs.
At the concert, she said, 'You're the worst singer.' Then she threw her drink at the stage.
She told the boy she liked, 'You're not even close to being good enough.' Then she sat down and said, 'I'm way better than you.'
