From the world of internationalperfumery. This word is used to describe perfumes which remind one of the sort of scented body oils one typically finds for sale at a head shop. Which is to say: potent, dark, synthetic, somewhat inelegant and indelicate, or blended to have a cloying, stale or lurid heaviness.
Perfumista #1: Have you tried that new perfume called DUNGEON?

A glass shop that usually sells pipes, bongs, everything hemp and incense, not to be confused with a shrink shop or head fixing(s) shop. In some states everyone has to insist they only smoke tobacco or incense in them, in other states people can be more truthy-ish. And you can get all sorts of CBD wax and tincture and candy in some.
