You Might Be a Brony If...

When someone does something that you admire or enjoy, you say “(Insert name) is best pony."

You suddenly find that you enjoy dubstep or rap.

You've ever, either accidently or purposefully, used the term "everypony" or "anypony" in a sentence while speaking to a non-Brony.

You have to say to "Forever" but feel the need to say "FOOORREEVVEERR."

You've ever had to choose between sleep and ponies, and chose ponies.

You can't help but giggle when someone mentions the word "plot."

You haven't been able to look at a cupcake or a rainbow in the same way.

Someone at a meeting mentions thinking outside of the box and you feel the need to bring up chimneys.

You have more pony music than "regular" music on your hard drive.

You work out to fanmade pony music. In public.

Your diet has suddenly included a lot more apples or apple-based products. (Ditto for carrots)

You used to swear, but now replace those words with phrase such "horseapples" or "a flying feather."

Fixed.

I stand corrected. Feel free to add your own, everyone.

You say the word yay and then automatically think of Fluttershy.

you think of rainbow dash whenever you see a rainbow.

you want to say yay very loud but you decide to do it silently

you laugh when playing amnesia.

you say ______ is best _____ instead of saying it in the correct grammar.

you see something chaotic happen and think of discord

Your Facebook profile pic is a pony.
You nearly/actually introduce yourself by your Ponysona name.
Think ponies are the answer to everything.
Think of MLP every time you see the word "pony."

You see the word "Scooter" and read it as "Scootaloo"

You see the word chicken and think of Scootaloo

You see a tree and think its Fluttershy

You proudly strut down the street with a pony tshirt on

You hum the theme tune at random moments

You seriously consider buying anything and everything pony related, reagrdless of price

...pony. Period.

...you join a pony based fleet in a star trek based online game.

I find that when I get really, royally cheezed at something/someone, I will usually comment "By Celestias right hoof.."

Nothing relieves your stress level like realising you now curse, pony-style

Touche, my good sir.

You carry around a different pony figure in your pocket each day, letting it remind you to focus on being a little better that day than you were the day before.

You slip up and say Everypony instead of everyone on occasion.

When something unexplainable goes wrong the phrase that comes to mind is, "I just don't know what went wrong!?"
When you absolutely agree with what is being said/talked about images of Twilight bounding around in circles repeatedly saying,"YES" are in your mind as you halfheartedly agree with a simple, "yes."
Constantly thinking about pony artwork designs you are working on and making them as accurate as possible...

...When someone calls you racist and tell them you have alot of friends who happen to be earth ponies.

You find yourself singing a song in class and it turns out to be the MLP theme song

While doing laundry you realize you own more pony shirts from WeLoveFine than regular t-shirts.

One morning you wake up and suddenly realize that where once your walls were adorned with framed pictures of places you've visited and awards you've earned, they are now covered in ponies. And you prefer it that way.

...you occasionally forget that your Ponysona name is not, in fact, your real name.

...you apologize for using "people," "everybody," "someone," etc., instead of "ponies," "everypony," "somepony," etc., when talking to other Bronies.

You buy a musical instrument just because your favourite pony has the same instrument

You wonder what it would be like to be a pony on at least a weekly basis

when you start to relate anything to ponys.

when your only able to think on ponys no matter the thing

When you fell like calling your dog Twiligth even if you know good thats not her name XD

A comment is made by a colleague, claiming an improvement of at least 20%, and you can't help but smile.

If while trying to write "Philidelphia" you accidentally write "Fillydelphia." (committed by my Chief Engineer, even though he refuses to acknowledge his acceptance into the Herd)

That's a common occurrence for me... since I live/grew up near Fillydelphia... and not helped by the fact that I often listen to Fillydelphia Radio while drawing.

And at work I have to cull produce... the voice and running through my head is Rarity's, saying "Lovely--horrid--lovely--lovely, etc..." LOL

When you try to become more like your favorite pony and be successful in doing so.
