The definition of popular expressions can change over time to mean different things to different people. For example, when my son says that I "yelled" at him, it can mean anything from a disapproving comment made in a normal tone of voice, to a louder, more alarming admonition. It can also mean shouting. Still, it is all "yelling" to him.

I've seen threads recently about being hit on and I wonder if it means being stared at appreciatively, ogled at, spoken to nicely, flirted with, winked at, asked out nicely, propositioned rudely, groped, etc.

Is it unwanted?

What's the difference between being approached in a social environment where the purpose in going is to meet people, and being hit on? Are they the same thing? And is it possible, depending on the level of self-consciousness, that an individual might think they are being hit on when in fact the other person is just wanting to make conversation whether or not they are testing the waters?
