The act of having sex with someone in order to have somewhere to stay that night. Generally done when visiting a new city/town when money for a hotel is in short supply.
I met this girl in a bar, she wasn't the prettiest but I only have two euro in my pocket and nowhere to stay so I had to bang for board.

My girlfriend kicked me out so I went to a club to bang for board

Get the Bang for Board mug.
A board that you show a person, and they magically run the fuck into it, causing severe head trauma.
"Tony pissed me off, so i showed him my fucking head bang board."
