Aggressive Power Chillen or "APC", is the action of actively seeking to max out one's chilling. eg: if you are regular chilling, sitting in a chair, you can transcend to aggressive power chilling by kicking feet up, slouching to the highest degree possible, and smoking/drinking whatever is around you.
