A system by where an item is taken out of service to prevent it from breaking down due to overuse. It is questionable as to whether work is actually being done or not.

Prefects

So there is the 5% of prefects, and of course the 95% of prefects.
5%: The normal good ppl including my best fren, but teachers are obviously still inclined to like them.
95%:
Bitches and sluts who wanna suck the cher's ass. They literally don't have their own opinions and are practically programmed by chers to be jailers and arrest all rule-breakers, minor or major. Many of them are in fact back stabbers and wannabes. They gather in large groups, and pretend to be loud and popular and funny. Other poor bitches who wanna be popular will try to join them. Most are idiots who the teacher likes because of the sash they wear, and as such they think that they are superior and in control like big bosses.

Me: *Harmlessly eating while using my phone in the canteen after school to contact my parents
Bitchy prefects: *Looks up from her phone and sees me (Shouting for everyone to hear) No using phone in canteen No using phone in canteen
