Someone who is obfoxious is like a bad pizza, a loud kid, and a broken radio all rolled into one. They make your brain hurt.
My neighbor is obfoxious because he yells at the TV and still thinks the president is a good singer.
My little brother called my mom obfoxious because she said his math test was bad and he got a C.
My dog is obfoxious because it barks at the mailman and thinks it’s a politician.
