Nadzilla
Nadzilla is the person who doesn't swear, but she still makes you feel stupid for no reason. She's smart, funny, and always knows when to laugh.
She said, 'You failed math? I passed it in my sleep. You're a disaster.'
She laughed so hard at my cat that my cat started purring at her.
She told my friend that his joke was so bad that it deserved a math test.
