I wouldn't dare
If you're sayin' I wouldn't dare do something, you're out of your mind. I'd eat a whole pizza for breakfast and a whole cake for dinner if it meant you got in trouble.
My dad said I wouldn't dare break his phone. I broke it and added glitter to it.
My friend said I wouldn't dare skip class. I skipped and told the teacher I was going to the moon.
My brother said I wouldn't dare eat his soup. I ate it and spilled it on him.
