Help, I am getting raped by a LAG

[tbaarslag]

Villain is running 30/25/3 and is raping me. I had no chance to find out if he is a good or bad lag.

He floated me 2 or 3 times before this hand and I chickened out every time and folded to his turn bet.

I expect villain to give up or bluff smaller, but he mashes the pot again. Does this have significant influence on his range?
