Villain seems like a regular:
16 / 12 / 3B 6 / AF 4
24 3B x Button Open
Looking back at the hand now, I see that I'm only losing to 77, AQo and AKo. This was more of a psychological fold, I guess, since several people have been drawing out on me and making these thin value bets which I end up calling "incorrectly". 
I guess I would be more prone to call if he shoves that when he bets this small; this certainly doesn't seem like a block bet at all.
