Have had many people ask me about the term BBW.  So, here is what I found...
"Big Beautiful Woman" (commonly abbreviated as BBW) is a neologism most frequently used in the context of affirmation of or sexual attraction to women who are overweight or obese, whose bodies have what may be considered excessive adipose tissue.
The term is a subjective, visually-determined concept that does not have an explicit lower or upper weight limitation, and may denote women who may be considered barely overweight to those who are morbidly obese.
The term BBW is also used to denote events specifically targeted to such women, and persons interested in them, such as specific gathering nights in dance clubs, restaurants, fashion stores and shows, etc so that an environment of acceptance is achieved by having like-minded or like-bodied persons in attendance.
The term has several near-synonyms with varying shades of meaning:
Full-figured or Rubenesque - the latter term referring to the art of Peter Paul Rubens, best known for portraying full-bodied women.
Voluptuous and zaftig usually connote ripeness, sensuality, and a body shape involving large breasts and wide hips.
