It's a term to describe the way a lady looks while still maintaining respect for her.
It means that she's dressed well and has the confidence to wear it.
Her head's up, shoulder's squared, and eyes have a strong stare.
A stount girl will make you smile for the simple fact that you need it. Then, that stount girl will kill it and eat it.
"Oh dat girl was lookin' straight stount last night!"
Yeah, boi! Her confidence was a stain you can't wipe off!
