Is this AQo play too aggressive this early? (Party 109s)

[Meatmaw]

I'm thinking my play was ok, considering it seems there's more than the occasional "I dare you" reraises to ~100 pot bets (without a killer hand). Am I incorrect to feel this happens enough in the 109s to warrant this level of aggression with this hand? Should I let him push me off this?
