I am a smoker (I know I shouldn't smoke but I do so you can save the lectures). I also know that people who smoke can stink. For some reason when you smoke outside in the winter it smells ten times worse than normal. I tried to look up the reason for this before I started posting this however all the links brought me to discussions on why people smell smoke that isn't really there (ummm ok) and talks of people's urine smell. Obviously NOT what I was looking for so I gave up (rather quickly at that).
Anyway, my guess is something to do with the cold air and it clinging to your clothes more (yes I am a rocket scientist). I used to date a guy (many many years ago), we will call him Stinky, who smoked like a chimney. I smoke but I can manage to breathe for a few hours between cigarettes. He smoked constantly. I worked at a retail store with him part-time. On nights that he wasn't working he would frequently come up to see me. He wore a heavy coat. It was of an NFL team that was NOT the Eagles. It was blue and gray and had a big fat star on it. Have you figured this out yet? I remember the coat vividly (which is impressive because I can't even remember his last name).
I always knew when he was there before I even saw him because the stench preceded him. Especially in the winter. I would look around and sure enough he would come around the corner. I really tried not to mention it since I am a smoker and I know that I stink too but I just stink like a cigarette not like a chimney. One day, I sniffed and looked up and there he was. I said " you stink" and he said "thanks". After that, I got progressively more grossed out because I have the nose of a bloodhound. He was more than a little needy and with the smell, he had to go. We broke up, he hated me but I didn't really care because, while he was a nice guy, he smelled and was needy.
I wonder what ever happened to "Stinky".... I would look him up but I can't remember his last name. Gonna go smoke a cigarette now....
