It is the same where I hail from in New Jersey and in different communities in Israel where I have been too (RBS is a well knwon example.)
IMHO what has become the “norm” is to “have fun” in high school and only afterwards do the right thing, despite the fact almost everyone committing these ill acts know its wrong from the start. I do not know where this came about, but many from my high school class and my neighborhood always have done this.
