To be royally screwed over; just when you think a very bad situation cannot get any worse - it does; a conclusion to a bad situation where the second and third order effects include loss of pride and manhood, etc.; a situation where one gets completely fucked over and all you can do is laugh and mutter under your breath, "FML" or something equivalent to that degree.

Word origin: coined after a man who has very bad luck
Example 1:
Jeff: So, I just got back from a deployment, and my wife left me.
John: That's terrible.
Jeff: Yeah, I know. She became a lesbian and left me for another woman. She also cheated on me with other women while I was deployed.
John: Dude, you got O-B'd!!!

Example 2:
Jeff: All the money in my bank account is gone!
Chad: Dude, that sucks.
Jeff: On top of that, I think someone stole my identity and opened up a few credit card accounts!
Chad: O-B'd again, Jeff.

Example 3:
Jeff: My parents just bought me a piano for my birthday. It was pretty cool at first.
Celest: Wow, that's thoughtful.
Jeff: Yes, but when I checked my bank account, there was a couple thousand dollars missing. Then I realized parents used my money to get me that piano!
Celest: You got O-B'd!
