The Art of Manliness recently had a great article on the 15 manliest smells.  Here were (understandably) my 2 favourites on the list:

Scotch: “The warm, rich, smokey smell of an aged scotch whisky [...], a scent that will put hair on the chest of any man who takes a whiff”

Pipe Smoke: “A whiff of a nice clove or cherry wood blend summons images of kindly older men in tweed jackets sitting in a chair next to a warm cozy fire with an old dog nearby.”

Some others that hit my soft spots?  The barbershop, shoe polish, and cut grass.  All things I can identify with.
