Cumin is a common note in many scents that people mention as smelling like body odor. Cardamom, another spice, can also occasionally generate this type of smell. And then, of course, musks of various kinds can also simulate b.o.
This said, I have to wholeheartedly agree that L' Eau d'Hermes smells somewhat like b.o., because of its' huge cumin note. I like cumin in my food, and don't mind a touch of it in a scent, but it is just over-the-top in this fragrance.
P.S. Welcome to these fora!
