Ah pledging/hazing, a double edged sword. A possibility for camaraderie and mentorship which is often misused for abusive and degrading activities. I went through pledging/hazing in a college fraternity in the US and it was mostly harmless if immature and crass, but for activities or challenges involving alcohol I could see it easy to go overboard especially at fraternities with a more macho/party reputation or with the wrong people involved.
