sure it's frowned on by the old ladies who frown on everything. but it still occurs a lot and girls fall for it, a lot.
btw same stuff happens in the usa, usually in bars, the kind that are called 'meat markets'. it also happens in the streets, colleges etc. often it's ignored and the guy doing it just moves on to the next target eventually finding one that either likes it or doesn't mind.
