This depends entirely on the BB's 3-bet range, which we do not know. Some people only 3-bet aces. Some will 3-bet any pocket pair (e.g. people who have read Phil Hellmuth's book). Some will 3-bet any ace, or any two broadway, hell any one broadway. Some will 3-bet suited connectors. You get the picture.

Since we know nothing about this opponent, I don't think it's necessarily bad to peel one off on the flop.

Now if we had a read that this player was solid, that would be a different story...
