Quelle est la OBX?

Just when I thought I could go a week without seeing an OBX sticker I see one a car over here. It was on one of the American cars so I'm guessing they had it on their car before coming over the France. Still I can't believe I saw one of those stupid stickers almost 4,000 miles from home. The French are probably like "WTF, Quelle est la OBX?!?"
