The acronym BBW stands for Big Beautiful Woman, and in common parlance, refers to all those curvy ladies with a larger-than-average physique; yes, it's slang for chubby, plump, and plus-size women.

The phrase is often confused with big-breasted female escorts in the strict sense, but that's not the case - though usually due to their extra weight.

Also, women with larger hips, belly, and breasts among female escorts with thicker, corseted women are also flagged as BBWs.
