On a night out I'll get guys coming up to me regularly and it does get kind of annoying but at least the majority take the gentle hints or pleasant rejections well.

What the hell am I supposed to do about the guy that absolutely categorically will NOT leave you alone on a night out.

I mean when you've told them what feels like a million times and you've been absolutely clear. It can be very intimidating when a guy is like this and I feel the advice "plow" is absolutely wrong, it's scary.

Thoughts seddit? What would you advise a girl to do about these guys?
