The act of rubbing your back against the edge of a wall to relieve tension and pain. It's a well known fact that violating your home's jagged edges relieves stress, improves posture, and alleviates depression. Studies have also shown that regular backsterbation increases sexual pleasure and rekindles lackluster relationships. Common side effects include missing socks and blindness.

Daniel: Aw, man. I guess I'll just have to resort to backsterbation again.
