Conehead

Today's Maxism:

Me: "How was your day?"
Max: "[kid-from-school-who-will-remain-nameless] was mean to me."
Me: "Oh no, what happened?"...
Max: "He hit me on the shoulder and said he was going to get ME expelled from school!"
Me: "What? Why would he say something like that?"
Max: "I don't know. I told him he was a conehead."
Me: "A conehead?"
Max: "Yeah, a conehead. (shrugs) It's a figure of speech."

I know only one person that says 'conehead'... Papaw!
