LIVE 100NL pretty flop facing huge overbet

Live homegame 100NL. 10 players
Villain is unknown to me and this is one of the first hands. He lost a chunk of his chips a few hands ago when he called a flop pot bet but folded turn so that doesn't say much.
I have A [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/heart.gif[/img] and limp in MP with 2 limpers ahead of me. Villain limps in the CO
flop comes
