There's actually a fragrance one can purchase called Obsession. I suppose that the idea is to suggest that by spraying oneself with this perfume that one becomes irresistable and this causes other people to obsess over you. The chances that this will work out in a positive way are pretty low. In fact, it's most likely that the wrong people will obsess over you and that you'll be stuck dealing with unwanted attention. It could be even worse than that since if the wrong people obsess over you and you repel their advances, things could get ugly or even violent. Sometimes things don't work out in the way imagined. In fact, often things go wrong in unanticipated ways - there being a huge gap between fantasty and reality - and so calling a fragrance Obsession might not be such a great idea.
