What is feen?

It appears there might be a typo or need for clarification in your request. If you are referring to "Feen," it could relate to various contexts depending on the subject, such as a name, a brand, or another category. Here’s some general information based on possible interpretations:

1. Feen (as a name): "Feen" could be a surname or a given name. Individuals with this name may have histories or genealogies of interest, though it isn't a widely recognized name and may not have widespread historical significance.

2. Feen in slang: The term "feen" is sometimes used as a slang variation of "fiend," which can refer to someone with an intense craving or addiction, often for drugs or something else they strongly desire.

3. Products or Brands: If "Feen" refers to a specific product or brand, more details are needed as there isn't a famous or widely recognized product or brand with that name as of my last update.
