1/2 6-max 65o in BB, flopped two pair gets raised

[34TheTruth34]

1/2 6-max on Full Tilt, villain has $164, I cover.

only have 42 hands on villain, he is:

38 VPIP
14 PFR
1.3 AF (Flop: 1.75 Turn: .5 River: 0)
18 WSD

Don't remember anything special from the hands he played.

He limps UTG, UTG+1 limps, CO folds, button folds, I complete in SB with 65o, BB checks. 4 players, $8 pot.

I bet $5, BB folds, UTG raises to $15, UTG+1 folds, I call. 2 players, $38 pot.

I check, he bets $22, I fold. Thoughts?

Loose table? Could the villian be limping with AK, AA, KK or was he just trying to see a flop?
