mad for it
Being mad is like being a brainwashed soldier. You don’t care if you get hurt, you just want to win, even if it’s over something stupid.
I’m mad because my brother got more pizza than me. I’m going to fight him.
She’s mad because her cat knocked over her coffee. She’s going to punch the cat.
He’s mad because he got a B on his test. He’s going to cry in public.
