I don't like the smell of very many things.
Almost everything that smells, smells bad to me. There are very few things I can list that I enjoy the smell of.
Good food and drinks, Certain plants (some flowers, wood, pine, marijuana) new car smell, some candles and that is all I can think of.
Anything else that has a smell, smells bad to horrible. I do not like any chemical smells including perfume or cologne, I do not like cleaners or any smell that comes from people or other animals, with the exception of meat.
Pretty much %90 of things I can smell are unsatisfying to awful.
