A 10 - 15 year old kid who thinks either watching or posting Tik Toks and Instagram vids of shitty JDM memes makes them superior to others. They must always find a way to show their internet expertise by always talking about the Mk4 supra, or the R34 skyline and other mainstream Japanese cars.
Mark: Bro do you even know what a RB26 is!?

John: Bruh Mark, shut the fuck up, you're 14 year old JDM fanboy who watches nothing but JDM related Tik Toks and Fast and Furious movies.

A console fanboy is a person who consistently claims that one video game console is better than the others, and insults anyone who plays one of the consoles he/she hates.

Ironically, anyone who calls someone else a fanboy is usually a fanboy themselves. An overwhelmingly common behavior in console fanboys is to call someone else a fanboy, and display fanboy behavior immediatly after (see example).

Unfortunatly, the term gets thrown around so much that few treat the word correctly now. Someone who says he prefers one console over another is immediatly called a fanboy. The most commonly forgotten fact is that fanoys are people who mindlessly trash another console and the people who play them for no reason, NOT people who are just expressing an opinion. Few actually take the time to tell the difference.
Example of the "Calling someone a fanboy and behaving like one right after" behavior:

Sane poster: PS3 and Wii are fun, but Xbox is my favorite.

Console fanboy: OMG us such a 360 fanboy!!! 360 fanboy alert! PS3 is better than both consoles, better graphics, better sound, better online, the other consoles are so shitty, it's unbelivable! PS3 is the ONLY good console, i say SWAT teams should execute anyone who plays anything else! God, stop being such a 360 fanboy!!!

1. A person who believes in almost anything that apple says and gives into it's marketing strategy. 2. A prime target for apple marketers to impose their superfluously costing products to. 3. A person who honestly believes that Windows XP or Vista is Archaic, Inferior, Does Not Work, or just plain ripped off ideas from the Mac OS. 4. One who waits in line for days in some instances, for Apple keynote speeches. 5. One who believes adding an "i" prefix to anything is automatically superior to anything that does not have an "i" in front of it.
Most apple fanboys will possess three or more of the following:

1. iPod
2. iPhone
3. Macbook
4. iMac
5. Mac Pro
6. 3 or more Apple Connector Cables
7. A membership at Macheist.com

All those little kids that spend their entire life and money on the Call Of Duty franchise. This individual:

1. Thinks that the only "kick-ass" game is Cod.
2. Is usually a fat potty-mouthed socially depressed kid and has fat parents who don't give a shit about his child's health and therefore let him play videogames all the time to keep him away from their lives while feeding him fast food from Mc. Donalds.
3. Thinks that he can go to the army and eventually kick everyone's ass without any kind of training.
4. Believes of himself as the best because of his kill/death ratio, or his high multiplayer rank.
5. Is doomed to live the rest of his life as a dungeon troll.
COD Fanboy's logic:

Maybe if I insult everyone, people will start thinking that I am a badass. "MOM BRING ME SOME HOT CHOCOLATE IM HUNGRY YOU BITCH!"

Everyone in the lobby:
*watch out we've got a badass over here*

An absolute idiot who thinks AMD is superior in every single way than Intel and Nvidia and don't know about other platforms advantages. They are one of the worst fanboys ever discovered and they are about 12-16 years old (most of them).
NOTE : Not all AMD users are fanboys. Someone can like AMD for their products and not being a fanboy.
Intel user : Hey, look at my brand new i9-7980XE!
Butthurt AMD fanboy : YOUR CPU SUCKS, NOOB. I HAVE A THREADRIPPER AND IT'S WAY BETTER THAN YOUR OVERPRICED PIECE OF SHIT!
Intel user : Bro, I purchased this CPU with my own money, you just begged a Threadripper from your parents.
Butthurt AMD fanboy : YOU THROWN YOUR MONEY AT THE GARBAGE, ANYWAYS! INTEL IS FOR GAYS!
Rational AMD user : Dude, if he wanted to purchase this CPU, is his decision!
Butthurt AMD fanboy : THIS IS NOT A CPU! IT'S AN OVERPRICED PIECE OF SHIT! AMD MASTER RACE!!!
