Plenty of brain dead players online. A hand from last night.

I had 77 pre and raised on the button 3X BB
BB called
flop came 2-8-7
I bet and BB made a huge (7X) raise. I had reason to think the guy was a calling station, so I shoved. He called.

He flopped 2 pair 8's and 2's. I understand protecting your blind but 8-2????????
