A Friend Group at my High School Calls Themselves the "HYPSM Squad"

So my school has an insanely competitive atmosphere. So competitive, in fact, that the administration forces everyone to reveal their rejection letters in a "wall of rejections." This one infamous group of people—perhaps the most pretentious bunch of people I've ever met—is determined to "defeat" everyone else in this "game" by securing admission to each respective HYPSM school that they are nicknamed after. Here are some pretty funny facts about each one:

Stanford guy: This one's the worst. As I mentioned in a comment, he wrote his commonapp about how his acceptance into Mensa International indicates he will gain admission into college. I also heard his "5 important things" Stanford essay was just the word "Stanford" repeated five times. Unfortunately (or luckily), I haven't talked with him much, and what I knkow is hearsay from friends, so I don't know much more about him. (rejected)

Yale: I feel bad for this guy. The other people pressured him to apply early to Yale instead of his dream school. He was rejected.

There is no MIT guy, and this group has a sense of elitism against STEM students for some reason.

Princeton: He was accepted funnily enough, as he had a pretty impressive publication in a history journal for high schoolers (after using a coaching service made by them lol). He has an aura of fake humility and once he undermined his presentation partners in order to make them look bad.

Harvard: Bro disputed his deferral and turned it into a rejection (most likely, I just assume he won't be admitted in Spring for his rude email).

EDIT: I should clarify that the wall of rejections is to destigmatize rejections, not humiliate people.
