Beastmode is when the inner strenght in you comes out, it could be rapping, skateboarding, it dosen't mean fighting and eating someone's neck that's a sick monster but i believe you must be sober when truly tapping into your power. It doesn't count when your on drugs, even a wimp can feel like a beast when he's high of purp.
