There's no way to tell someone "I don't like the way you smell" without coming across as "you stink."
I'm with NYC. Why the hell would you need to tell someone that? You don't have to explain why you don't want to date someone. "I don't think it's going to work out" or "I don't think we're compatible" is not bullshit. Bullshit is lying.
