This is when you're so annoyed you could scream, but you just say 'Nah, it's cool' to make it even more annoying.

My friend spilled soda on my shirt and I said 'Nah, it's cool' even though I wanted to scream.

My teacher gave me extra homework and I said 'Nah, it's cool' just to be annoying.

My dog chased my cat and I said 'Nah, it's cool' because I was too annoyed to do anything.
