I don't know, I see it as very unlikely to get insulted that way. People are usually much more subtle than that anyway. I'd probably ask them to repeat what they last said again, and if they've got the guts to do that, ask them why did they say that. I don't know what happens next . In the worst case scenario that could escalate to a physical figt; scenario that I'd avoid unless it's inevitable.
