A way of saying you’re so unimpressed, you don’t even want to talk about it anymore.

Your math test was bad. I don’t give a brass razoo, I’m gonna draw a mustache on your face.

You didn’t clean your room. I don’t give a brass razoo, I’m gonna throw your socks at your teacher.

You said I’m ugly. I don’t give a brass razoo, I’m gonna text you a goat and a middle finger.
