An angry, loud noise in your head that happens when you do something so wrong it makes your brain yell at you.

I spilled my drink on my shirt and now I look like a disaster. My brain yelled at me.

I tried to be a superhero and tripped. My brain is now a laughingstock.

I told my friend I was a dragon and now I have to live with that lie. My brain is now a dragon.
