This actually counts as a kind of culture.
If a college student wants to have a certain future, they must join various clubs and Brotherhoods during university. But they don't join these organizations to experience life; they're mostly there to be servants.
Also, joining requires going through an obedience test, where newcomers are asked to do outrageous or demeaning things.
They might be asked to publicly confess to an unattractive girl or to spend the night with her, or even to run naked around campus.
It seems like a prank, but in essence, it's an obedience test.
If you obey them and accept their decisions, then you are the person they're selecting.
If you feel insulted and dislike it, then, okay, you're not the one they're looking for, and you can't join their organization.
After graduating college, those who joined these Brotherhood organizations receive recommendation letters from classmates, enter big companies, or start new lives in government agencies.
