well suggesting that since im the girl, and my 尻, お尻 would get slapped. note to every one who has ever gotten sexually harassed または sexually abused in public in a place with a lot of people, または even a few people.
when they touch you, say what they're doing out loud, dont be scared または embarrassed, if あなた cause others to bring their attention to あなた the person will probably stop doing what their doing, and the group of strangers may even go up to him.
