I occasionally use redbull as a sexual lubricant and some tribes in Malaysia use redbull tipped darts when hunting for food. When redbull hits the bloodstream in most large game, it causes immediate hyperactive stroke and any animal under 70kg usually can not survive. According to one source, the CIA used redbull in the 70s as a super potent "mace." when drinking redbull simply spit or spray someone in the eyes at close quarters with a mouthful of redbull and they may never see again. Be careful not to miss though! works well as an insectacide too.
