obnoxius - A loud, grumpy feeling when you make such a huge mistake it

A loud, grumpy feeling when you make such a huge mistake it feels like your brain is throwing a tantrum.

I forgot my lunch and ate a whole pizza. My brain is now a pizza monster.

I tried to be funny and said 'I’m a vampire.' No one laughed. My brain is now dead.

I drew on my face and went to school. My brain is now a masterpiece of chaos.
