Hazing, the submitting of initiates to indignities at the hands of upperclassmen, is a part of rites of passage. As a pledging rite, the freshmen, or fraternity pledges, prove their worthiness to be members of that particular body, by partaking in and going along with ridiculous, self-debasing acts. By doing so they show that they can and will confirm to the authority that governs that body.
Example:
A: What's Hal doing in a bunny suit?
B: Don't you know? He is a pledge to join a fraternity, and he's going through hazing.
A: Man, I guess I'll never join a frat. I'm not ever going to let somebody make such a fool out of me.
B: Perish the thought. You're doing fine all by yourself!
