NAH NAH NAH!
A dramatic sound I make when something bad happens and I don’t know how to react, so I just yell it out.
Nah nah nah! My dog ate my homework and now I’m gonna fail!
Nah nah nah! My best friend is cheating on me with my enemy!
Nah nah nah! I just got a 50 on my math test and I’m gonna cry.
