First thing: Minimum raise = bad. It's weak and is not going to represent any strength by you nor is it going to make anyone fold. I would be folding Arag offsuit UTG. Although at those lower blinds I do find myself loosening up on my starting hands so I may have tried to limp.
Secondly, I think it was a terrible call by Rockfly with QJo. He may have thought that thakilla was just trying to buy one being that he was pretty short-stacked so he thought he would gambe and it didn't work out.
