Sometimes, it's better not to say anything.
Telling a woman how large her ribcage and calves are isn't the best way to get on her good side. Yet some guys think it is. Seriously.
Compliments are awesome, but more often than not, clueless guys can dish out something that sounds far more like an insult than something a woman is psyched to hear. I asked a handful of women the worst "compliments" a guy has given them. These are the six dumbest. But since I kinda like you, I'm going to clue you in on what you should say instead.
#1. "Wow, you have a really big ribcage!"
A guy said this to me on a fourth date as things were getting hot and heavy. I'm not sure if he was trying to compliment my boobs and chickened out, but regardless, no girl wants to hear the word big in reference to her body. And yes, that includes talking about her boobs. I mean, seriously: a really big RIBCAGE? What does that even mean? Should I see a doctor? Am I going to be okay?
