Cake can leave a sticky residue, and clots behind the ears, but it does lend a sweet aroma, and others may think it’s your birthday and treat you accordingly. Keep in mind that everyone has specific chemistry, and even if chocolate cake is your favorite, it may not compliment your scent. You may be more of a spice cake person. This may seem overly particular, but learn from Dog. Dog is very choosey about which stink he rolls in.

Dump out your piggy bank on the floor. Loose change offers a coppery, metallic scent to those who anticipate a need for toughness and rigidity. Going into a tough meeting? Want to smell like the Terminator? Loose change is probably the scent for you. This is also an option if you are dating a robot.

Smell like your favorite sport. Soccer, baseball, hockey. Scents can be layered, so find several places inside the stadium or arena in which to roll. Come away smelling of grass and the wind and peanut shells and hot dogs and spilled beer and sunscreen and facepaint. This scent will present you as the avid sports fan you are, and can be especially erotic when one wears nothing but a scorecard.

Try rolling in your favorite city. Living in cities like Denver and Chicago, there is probably already a hint of pollution about you. Start in the parking garages and work your way up to the clubs and then the club patrons and then the boutiques and then the coffee shops and then the homeless and then the parks and then the public transportation system. Make up combinations of your own. Dog will be proud.
