That insulting eh?

What I'm saying is that you can't turn it into an insult because it doesn't makes sense. Example that is very similar to the situation.

Me: "Nobody is more badass than me."
You: "Oh, you're that badass?"

Which is obviously not insulting.

One more attempt:
Me: "Nobody fails classes in school less than me."
You: "Oh you fail classes that much?"

Try to understand, that when someone is 0 of something that is considered bad, it's a good thing.

What is it they say about silence being golden?
