Stanboy 

Stanboys are the most overzealous among all fandoms due to their extreme nature of loyalty to certain objects of affection. Stanboys differ from stans, and -fanboys due to rabid nature. While fanboy's loyalty can change from time to time, a stanboy has absolute refusal to try anything that differs from their liked object.
Similar to how apple fans will refuse to touch any droid device, marvel fans refuse to watch nondisney filmed comic movies from rival brands , or consoles stans who refuse to play on a console not their favorite brands.
Stanboy behavior is often on par with the behavior of the "TWIHARD" fandom during the late 00s where twilight fans assaulted non-fans who criticized the movie and books with physical violence and various weapons.

Student A: Hey let me give you my number so i can give you directions our study group tonight

Student B: sure let me see your phone

Student B: ...

Student A: Is there a problem?

Student B: Yeah i don't touch non apple devices

Student A : Are you freaking kidding me?!? Don't even worry about it stanboy

Student B : Just find someone with an iphone so I can get directions

Student A : nah hard pass dude.

Stanboy 

A Stanboy is an overzealous person who's in a complete obsession with Person, Place, Product, or other like objects.
Stanboys differentiate themselves from fanboys due to the extreme obsession. While many fanboys will at least still try other products including their rival one's time to time. Stanboys live with the notion that whatever they prefer, is the one above all for said categories and will refuse to try anything that rivals what they enjoy. Stanboys are often confrontational when in the presence of anything that rivals their likes, and often believes the rival should be executed for simply not enjoying what they do. This was common during the release of the Twilight films and Books where overzealous, "Twihards" had attacked nonfans with flareguns, attempted stabbings, acid being thrown on another, and jumping of a girl in a Wal-Mart. Despite many companies not caring for the individuals, many Stanboys will defend whatever object of affection blindly even if said item is of absolute garbage quality.

This is common among the following groups of fans/stans:
K-pop

Marvel Cinematic Universe
Disney
Apple

World of Warcraft Players

Weeaboos/Wapanese
Metal "Fans"
Gaming Console Fans
Twilight community
Dragonball Z fans

Chris : Have you seen that new end game movie
Kimberly: Nah, superhero movies have kind of burnt me out, though I may watch it later
Chris: Why later and not now... It's the best movie of all time, it has broken more box office records than any other movie to date.
Kimberly: Chill dude, like calm the heck down I just said I would watch it later.
Chirs: People like you should die, Disney built something beautiful and life-changing and you're not even appreciating it
Kimberly: That's cool, like whatever, I think I'm going to watch the Joker instead now.
Chris: YOU PIECE OF TRASH PEOPLE LIKE YOU SHOULD DIE FOR EVEN WATCHING THAT DC GARBAGE ITS NOT EVEN ORIGINAL ITS A MANIFESTO FOR INCELS AND WHITE TRIGGERED WHITE MEN!
Kimberly: Frist off you're white, and a literal incel, and a male. Not that I care about stuff like that, but I'm going to watch the Joker either way. Stan away Stanboy

Seanboy 

A nickname that is often used, by either parents, relatives, or their friends, to refer to people with the name "Sean" when they were a child. The nickname seems to never wear off, and is often a source of embarrassment for the person in question when a parent uses it to address their child in public.

"Dude, did your mom just call you 'Seanboy'?"
