Nah, it's cool
This is when you're so mad you could cry, but you say 'Nah, it's cool' to make it even worse.
My dog bit my friend and I said 'Nah, it's cool' even though I was about to cry.
My brother broke my phone and I said 'Nah, it's cool' because I was too mad to care.
My teacher gave me a pop quiz and I said 'Nah, it's cool' even though I was about to cry.
