Baked On Road Crud. The accumulated heat-hardend road debris usually found on vehicles around engines and their exhausts. ** This is an Acronym (a word combing the intial letters of what it references) and Onomatopoeia (a word thats sounds like what it is describing).
Hey Chris, you should clean off the borc before you remove the sparkplugs or it might fall into the engine. (Thanks dad!)
