50nl KK vs very agressive player

[prodonkey]

Villain is 36/16/9.5 over 160 hands.. so very agressive, but he limps the CO on this hand..wtf??

Had just sat down at the table maybe 1 orbit earlier and hadn't played a hand that I recall, maybe stole the blinds once.

Should I just re-raise the flop and hope to get it in there? I figured this was a WA/WB situation.. so I'd just let him bet, then pretty much the worst 2 cards in the deck roll off on the turn and river for me.
