Lines from the show you quote often?

[Mrs. Prospector 20]

I was just thinking about how I'll often say "Congratulations, X, you're the new Y", referencing the "Congratulations Spike, you're the new Rainbow Dash" line from Return of Harmony. It got me wondering if anybody else will subconsciously reference MLP quotes in their daily speech without necessarily realizing it.

[cuteycindyhoney 13,283]

I have slipped and said "Everypony" a few times. That's about it.

(Gets me weird looks)

I don’t quote the show often at all but I love this exchange:

“She'll be come a crazy cat lady!”

”She only has one cat”

”Give her time...”

[Gaines 1,110]

"Sweet Celestia!" 
"What in Equestria...?" 

[Ittoni 536]

"treat him like the dog he is!" - Sweetie Belle 

[Cagey 4,207]

“Laughs don’t come in barrels. They come from inside you as your body’s response to delight.” 

[Jesse Terrence 2,963]

I have one that I use quite often.

"Eeyup"

[EpicEnergy 22,076]

I say "everypony" quite often when chatting with other bronies online like here on these forums.

Does Marble's "mmhmm" count? I'm not intentionally quoting her, but I say it a lot (and often remember that that's all she says).

If the way you say it sounds similar to her tone then I suppose it's a quote

I have found myself saying on uncomfortably hot days...

"It needs to be about twenty percent cooler."

[Courageous Thunder Dash 7,809]

I say "What the hay?" A lot. 

I do reference the magic of friendship a lot.

I've used this a couple of times on the forum.

I also like Twilight Sparkle's deadpan "It's summer." from "The Ticket Master". 

[Splashee 28,537]

Twilight Sparkle win the crown!

[TheAnimationFanatic 3,543]

"I'm too young to grow up!" and "No. On so many levels, no."

[Rushing cash 824]

I once said to someone jokingly: "uhh. So much black, we get it, you're sad".

At times a quote lines from the show but not intentionally, I just realise it later.

I find that I say Discord's "Reeeeeeallly,,." a number of times.

[Ittoni 536]

I actually say "what the hay" on occasion, and Applejack's "what in tarnation" is contagious. 

[Splashee 28,537]

Twilight Sparkle Steal The Pearl

 

Spoiler

I made that one up, but I stand by the fact it was the most stupidest thing she has done after becoming a Princess

 

[Flying Pencil 3,023]

For me its "What the hay", but I don't say to much.

“And WHY didn’t you stop them?”

”Because you didn’t ask me to”

[Cash In 21,511]

I'm pretty sure I've said "Eeyup" plenty of times without even thinking about it. I guess it's ingrained into my mind at this point.
