Also known as the GCP Blend or the GCP. Refers to a gravity bong that is of the waterfall style. This bong is filled with a liquor such as wine, beer, or JD, which is then emptied into the hitter's mouth from the bottom hole (waterfall, carb). The resulting smoke is token from the mouthpiece, and brain cells rapidly die.
