Is yesterday’s hazing today’s assault?

I remember back in high school when one of the freshmen would leave the shower about six people made up of seniors and juniors would bum rush the hapless kid and toss him buck naked into the towel bin. Then we would quickly roll it into the girl’s locker room. Other times about four or six of us would roll our towels into rat tails, and lay in wait behind a bank of lockers and when the mark passed by, we would spring out and light his buttocks up with the rat tails. None of the freshmen never complained, neither did we, when we were freshmen. It was just something you knew to expect happening. I wonder if today they would view it as some assault? It was all in good fun, no malice intended. With schools having zero tolerance on this, and or that, is hazing now criminalized?
