Why do your farts smell good?

Smelling good or bad is rather subjective here (as for every other senses of aesthetics), and some most controversial smells I've learned up to date include: human body scent, gasoline, A. Durian (fruit), ... No, there is no fart in there lol. Some people find one of those appealing while others would throw up anywhere 2 metres near.
Then there's acquired smell whose mechanics I'm not so sure about.. Probably because it's unanimously an annoying smell therefore you have to learn to not hate it.

My fart? No, I don't think it smells good, or anything close to that. Good thing I have a fan on full blast with me at all times, so whenever it slips out the wind will carry it away to some unknowing victim.
