BBW stands for big, beautiful woman. Why does a site like the Urban Dictionary post negative definitions like this? (See below).
How do you know what’s humour, what’s serious and what’s over the line?… Substitute something else for “fat” or “black” or “Mexican” and see if it still sounds okay. Changing one descriptive word can do more than just change your perception.
Fat itself is not a bad word. The words around it change the sense of how the word is intended.
How would you write about a fat character?
What are your own preconceptions about people and how do they influence the way you write?
