What defines the soul in many religious endeavours is very different. In xtianity, as I think you may be referring to chicken, it is the essence of a person unrelated to the mind and body.
The term seems well used in popular culture, I have an idea what someone would mean by calling something or someone soulless or having no soul.
It's a problem for critical thinking skills which are in danger of rusting from disuse in modern society. Personally I uphold their importance.
