Do guys touch a girl to get her to like him?

My friend told me she heard that guys will touch a girl, whether she is their friend or not in order to unconsciously get a girl to start liking them. If a guy likes a girl and finds ways to touch her and she is ok with it then guys continue to do it thinking one day she will want to go out with them. Is there any truth to this?I know some guys are just friendly that way and it doesn't mean anything but aside from those guys, is it generally true?
