I think it's a brilliant move by villain. There aren't many hands that can call him there, actually no hand without an ace. Since you limp/raised he can eliminate hands like AJ and weaker from your range, even AQ is unlikely.
So he thinks you either got AA, AK, or you fold (as long as he believes that your a good player who won't make a crying call with Kings).
There are a lot of hands he can make this play with and i really like his move.

Sometimes he has you beat, sometimes he's pushing you around. Don't know what's more likely.

Still fold this I think and wait for a better spot.
