When you're so stuck on one thing that it physically hurts you and you start throwing insults at everything around you.

I was so stuck on my favorite band that I threw a shoe at my brother. He didn't like it.

I got so stuck on my pizza that I yelled at my cat. It ran away.

I was so stuck on my crush that I yelled at my math test. It failed me back.
