What does patchouli smell like, and why does everyone hate it?

I've owned and smelled a lot of fragrances, but I recently learned that patchouli is a dealbreaker for a lot of people. I just got into the hobby last year. Maybe I've smelled it in the past and just didn't know? My current fragrances don't have that note but not because I avoided patchouli. What do y'all think about this note?
