I'm gonna have a cow
A way to say you're so mad or happy you think you're about to start mooing. If you're stupid enough to believe you're actually raising cows, you might be asked to show them off at the next family reunion.
I had a cow when my dog bit my uncle.
When my mom said I had to do chores, I had a cow and a half.
I saw my crush and had a cow so loud my teacher yelled at me.
