A situation where the person you're sleeping next to in bed slowly occupies more and more of the bed throughout the night until you've been pushed all the way to the edge, leaving you with very little of what was once your side.
I didn't get any sleep last night because Brooke's pregnant and she tossed and turned, almost West Banking me off the bed.
