*Heavy set = overweight
*Stout = overweight
In Appalachia we use heavy set and stout to describe someone who is overweight.
A few weeks ago, I watched a video about Appalachia's colorful language. The gentleman being interviewed looked to be in his late 60s or early 70s. He said his grandmother used the word stout to describe someone who was overweight. He said he didn't hear many people use the word to describe an overweight person now these days.
Using heavy set and stout to describe an overweight person is still alive and well in my area of Appalachia. Why do we use the terms instead of just saying someone is overweight? Because we often go to great lengths to keep from offending anyone in our daily conversations.
