That's a good definition - and why should someone be subject to unwanted, multiple advances? In college, my older sister, who was very pretty, was "stalked" by a guy who just wouldn't give up and wouldn't take no for an answer. He was a bit of a weirdo, and even came to the house several times and became a pest. Its happened to several women I know.
It ended old school style when my older brother and a friend threatened him with a beating.
The critical element to me is, “wouldn’t take no for an answer”, in all walks of life.
