The only thing you can do is reraise him.  Hopefully he'll fold right there (if you raise enough).  If not, the same logic he is using to steal applies - he's forced to hit a flop.  And if he's stealing your BB form the SB, you even have position on him.  He checks the flop, you bet and take it down.
