obtusnoxious
A person who is not just annoying but also clueless and refuses to get it even when it’s handed to them with a smile and a curse word.
Why don’t you just die? I asked. He said, 'I don’t know what that means.'
She explained the joke three times. He still didn’t get it. And he called me a baby.
He insulted my mom, then asked why I was mad. I said, 'Because you’re obtusnoxious.' He said, 'What’s that mean?'
