flirting is a stupid word because no one knows the true meaning. When does something change from being harmless fun to being flirting, everyone has different opinions as to where that line is.
So in some company you will be accuesed of flirting and in other company you are just seen as having fun.

Why do you consider flirting something to be “accused of”? Flirting is fun. I flirt with most of my friends, and probably random complete strangers, too. Flirting doesn’t necessarily have to be seen as having alterior motives. I never have an alterior motive. Unless I’m winking at Matt. *laughs*
does continually elbowing someone on a train = flirting, or just being annoying???

flirt: To make playfully romantic or sexual overtures

yes, that would make it annoying by ryan’s definition
I think flirting is mostly harmless fun. It could have sexual overtones, but by that time it’s probably moved into being a “pass”.
