You're always crushed on turn, and gay bet means "plz plz plz don't fold, I haz the nuts".
First thing that I thought of when I seen that bet was maybe he was trying to pot control but its just not worth it. Way too many draws got there on the turn that hit his range hard. Looks like he is just setting up for an river push with 17 or so left behind.
He hasn't found a hand to raise in 40 hands, so I think we can put AKhh, AhA and KhK in his range. Passive villains like this I tend to play very straight up and just get out of the way when they bet.
