What are Pharemones?

I hear Pharemones are generated by animals and humans, but what are they for anyhow? Are they like, the smell of sweat?

IANA-Scientist but Pharemones are the smells we emit [or the smell anything emits] carried on the microscopic chemical level. Perfumes and such base themselves on the idea people are in fact highly influenced by our sense of smell. Social behaviors are based in some part on smell and of course what we eat as well.

But Pharemones are part of the non-perfume or non-synthetic smell we give off, and yes I do beleive sweat plays a role…
