A person, more often a youtube-user who hates the My little pony : Friendship is magic show.
An anti brony will insult and promise death to any brony. Their favourite insult is saying the bronies are homosexual. They will post hating messages on any MLP : FIM video on Youtube.
Similar to hater.
What they think of bronyhood is : (from a DeviantArt fanart)
"Killing peoples makes me cool but loving ponies makes me gay." This ideology is looking like the 1940's NAZI ideology. If you are a brony, he will try to force you into becoming a non-brony by insulting you, threatening to kill you and saying you're gay. You can't ger rid of a anti brony by conventionnal means. You need FRIENDSHIP!
anti brony : Bitch! shut yo mutha phukin skinny white boi azz up cause if you was walking down tha street I would bust a cap up in yo mutha fukin head dis is my musis ain't no white boi gona tell us OG's to turn our gangsta azz music down yoo feelin me?
brony : Who are you calling bitch? Try again, I dare you, and I will call all my friends.
anti brony : LOL U AND UR FRIENDS ARE FAGGOTS I WILL TRAP YOU IN A BUILDING AND SET IT ON FIRE YOU SCUM YOU SUCK I SHOULD KILL ALL BRONIES
bronies community : Be defeated by the power of friendship!
*anti brony turned into a brony*
Now, there are two ways to deal with a brony (a male fan of My Little Pony). You could either say "lol Internet" ignore the bronies, and call it a day, or you could take the more comical route. This definition covers the latter.
Before butthurt ensues, there is a big difference between someone who dislikes bronies, and being an anti brony.
Anti bronies will specifically go out of their way to spew whatever they can against bronies to the point of making their own anti brony Facebook pages, YouTube channels, (I shit you not) anti brony Call of Duty threads, and whatever they can get their grubby little hands on.
They are typically found in the ages between 10-30 (mostly 13, go figure) and, like some bronies, are the most annoying things you can find on the Internet.
Not only will they spam anything pony-related, but they make their own (albeit shitty) anti brony rap songs, anti brony Minecraft servers, even break the fucking law to deface pony murals, and so on.
Anything that a brony might do that annoys you, anti bronies have sure covered it, except it's a thousand times more annoying because, well, at least bronies enjoy themselves when they do pony-stuff, they don't watch My Little Pony to write bios with (LITERALLY) over 9,000 characters in text why the show sucks.
And if you still don't believe me, go on YouTube and search "mlp sucks". The first video is a chubby 10-year-old in his basement whining in front of a camera. And the rest of the anti bronies are afraid to show themselves (lol).
And this is coming from somebody who isn't a brony anymore.
An Anti Brony is a person who hates bronies. To rebut that they're "...who hate the show My Little Pony: Friendship is Magic..", as a brony stated, the definition is clearly "Anti Brony", not "Anti MLP".more...
There are many, but overall only one reason why bronies are hated; Their huge pride and endless bragging.
Anti bronies hate bronies because of their small sense of empathy. They can never agree with anything that an Anti Brony says, even if it's true.
Another, more common reason would be the massive load MLP:FiM related stuff in the internet, and how bronies have an obsession to shove it into people's faces.
(Example: Here's a real, translated comment sent by a brony on Pelaajalehti.com.
"There's a typo in the news: It's written BRONY not broyny or at least my shirt at the moment says Brony.. "
(Rational stuff about the article)
"And finally: Haters gonna hate.
PS. You stole my desktop wallpaper for the news pic...")
Even if you're watching a Garry's mod video, a Team Fortress 2 gameplay/music video, it's not unu...
