Its apparently the made up 'MLP's people make.

I think its happened. We're getting old.

male version of my little ponies

Its just people who are fans of the latest my little pony series (friendship is magic); I'd recommend watching a few episodes if I were you, :p

a Bronie is an adult person who is into MLP
note adult swim said Furries are still worst than Bronies

One of us.... one of us... join us.... join us ....

Lauren Faust's recreation of My Little Pony has garnered a tremendous fanbase, reaching even as far as adult males. Male fans of the show typically call themselves "bronies" as a way of identifying kindred spirits. A combination of "bro" (platonic male buddies) and ponies (the characters of the show).
*ahem* I am also a client--er, one of them.

Ah I thought that was the explanation too...

im 17 and i dont know either.

Christ in a hammock, don't join this fad. Nothing good will come of it, I swear!

I think that term is used because there are supposedly no women on the internet lol. Any fan of MLP is a brony.

Annoying fanbase that is ruining an enjoyable reboot of a cheaply made product cash-in show from the 90s.

Worse than Twilight fans.

The new MLP doesn't suck, so, some of us are a lil' over-excited.

Am Internet term usually reserved for adult male fans of the My Little Pony: Friendship Is Magic series. The show has garnish an enormous adult fanbase on the web including an unusual amount of guys. Often the term is extended to all adult fans regardless of gender (it is a fluid term).

Whole series is on Youtube if you wanna see, as with everything else, just something you'll want to decide yourself if its something you'll like, dislike or be indifferent to.

Yeah, I am a fan. :P

Run. Just run. Escape while you can. I'll hold them off.

Nothing to see here. Move along..

Just bang yourself in the face with a framing hammer for an hour and you'll get the idea.

I approve of this message. ^.^

Like others said, it's male fans of the show. Granted a lot of girls call themselves that, as if the title means you're a "real" fan or something like that. (i just think of it as being the retarded cousin nobody likes to talk about) Don't get too deep into it, just enjoy the new MLP for what it's worth and you'll do fine.

They are an internet scourge!

no not the bronies they are taking everywhere

The show isn't bad the animation is surprisingly good which is probably the most surprisingly part about the show. However, its aimed at too young an audience for me to really be interested in it...

RUN! RUN WHILE YOU STILL CAN JODIMEST!!!!

Not everyone likes it. (detractors primarily being those who haven't watched it)

If you want to try it out, which I would suggest, simply pick an episode off of the viewing chart, and head to Youtube.
There is a simple chart to explain which episode to start on, and how to proceed accordingly: Viewing Guide
(Winter Wrap-Up is fantastic, but I'd also suggest starting at the beginning just for introduction's sake)(The episodes can be watched out of order save for the pilot and the finale)
You can find all of the episodes here.

But take these with a warning: It turned The Internet Hate Machine into The Internet Friendship Machine in ten seconds flat.
Just set aside your preconceptions and reservations, and feel free to have fun. When your first episode is over, there will likely be a tiny voice inside your head urging you to follow the hyperlink to the next episode. Heed it's beckoning, and you just might find an enjoyable show worth watching. It's fun, light-hearted, adventuresome, and sends a great message of friendship and toleration that just might make the world a better place.

I'm afraid I have emotional diabetes :(

Too much sugar with my entertainment causes me physical harm. I approached carefully, tasted, and couldn't handle it. I won't pass judgment on the folks who like it, though.

Lol, shucks.

It's highly respectable that you tried it out at least, and we all appreciate the consideration you give us. (always welcome, but never obligated)

I should do my thesis paper on this.

I hope you have a high tolerance for such things, then! I approached it empirically and got burned

Ive had to read journals by unempirical "scholars" who think Castro and Chavez are saviors and that we invaded Afghanistan to build one friggin oil pipeline.

Hell, youve got to have a high tolerance just to be on FA.

Yes.
