How much do you hate this call? Sunday Warm-up

[Patrio]

Sunday warm-up, been playing for an hour so I know villian to some degree. He is a weak-LAG (doooonk, any two broadway is good) who I have seen overbet with his draws when missed on the flop. I fold this everytime to an unknown villian but somehow I trusted my read so much I just had to call. (I cant say what I put him on just yet)
