Contrary to what your girlfriend or the person at the department store will tell you, don't spray a cloud of cologne in front of you and step into it. That would be the wrong way to apply a scent. It wastes the product and it covers your carpet (and your knees) in fragrance. And no matter what your buddy claims, there's never a good reason to put cologne on your balls. Herewith, a few dos and don'ts.
