rolled up

[Bartholow]

I think reraising here is giving your hand away too much. Actually that's not exactly right. It would represent SOME strong hand. If you had reason to think your opponents woudl play on despite thinking you have aces down or something, then you could reraise because it DISGUISES your hand in some sense. But here it's too likely that they are both not that strong, and you'll get a fold on 5th too often.
