We all have the experience with it. When the nicotine stained hands of your boss find their place on your desk to discuss some paper work. When you're face to face at a coffee ring infested desk of your teacher talking about your grade. When you wake up next to the being you cant wait to spend your time with and they roll over for a kiss..... and they all breath on you. What is the worst kind of breath? Me personally I'd endure some of the nastiest kinds out there, but cigarette breathe usually makes me want to wrestle the person down and drown them in Binaca.
