At least he can spell, right?

While eating dinner...

E: "Some kids at school were saying a bad word today."
Me: "They were? That's not good."
E: "Yep. They were talking about TFC (Texas Football Club) but instead of saying football, they said a different word that starts with F."
Me: "That's a really bad word. I'm glad you weren't saying that word."
E: "Oh, I know. Do you know which word I'm talking about?"
Me: "Yep. Not good."
E: "The one that starts with F and the next letter is U?"
Me: "Yes. Not a good word."
E: "I know. I would never say that. The next letter is C?"
Me: "No more spelling. I know the word. It's definitely a bad one, and I'm glad you know better than to use that word."
E: "Well, yeah. I'd get in big trouble if I ever said the F_#_#_# word."

Me, staring blankly at him.

E: "That's the word you were thinking of, right?"
