The word itself derives from the high quantity of low quality cocaine found in the eastcoast North America in the early 2000's. The granular and low grade texture had customers likening the product to cement. The word also comes from the process of making cocaine itself, in Coloumbia, Bolivia, and the other Cocaine nations, a cement mixer or washing machine is often used to transfer cocaine from leaf to liquid resembling cement. Once the product is exported it is then cut with cement, asprin, baby powder and actual pure cocaine.
