Hmm coffee seems to be a popular one, funny someone mentioned gasoline, my daughter loves it too, it worried me a bit lol.

A few of you mentioned vanilla, it is one smell i cannot bear, although i quite like it in cooking, but not for perfumes or any other thing.

I love the smell of my azalea bush, it is rather strong when in flower, but it is a sweet smell, oh another i like is candy floss.
