Come on, admit it. You could fart right now and not even raise an eyebrow on its rotten smell. Sometimes you wouldn't even feel "successful" if it doesn't smell at all. I even know some people who would cup their behinds just to smell their own. But if someone else rips a nasty one, we would be gagging like crazy. Why do we like it? Is it psychological?
