Bronies React is a YouTube series, created by user ACRacebest originally as a response to "Teens React to My Little Pony: Friendship Is Magic". After the popularity of the first episode, more were made, and the series became more original rather than being just a Follow the Leader. Each episode has Race and several of his friends (often changing each episode) reacting to various things related to My Little Pony: Friendship is Magic, such as popular fanmade content or important episodes in the series.
Absentee Actor: The Bronies React to "Equestria Girls" was notably the first episode in which The Living Tombstone did not appear. He doesn't appear again until the reaction to the season 4 finale, likely due to being busy with various projects.
Big "YES!": IBringDaLulz reacts this way when Chrysalis defeats Celestia.
Call Back: Sometimes, references will be made to the cast members' individual works. For example, in the reaction to the season 2 finale, Solrac sings a bit of This Day Aria in the way he hasbecome known for.
Driven to Suicide: Played with in the Equestria Girls installment. When the silhouettes of the human Mane Six appear during the opening credits, BlackGryph0n takes out a knife, puts it to his throat...and then scrapes off some stubble, saying that he forgot to shave that morning.
Early Installment Weirdness: The first episode (and, to an extent, the second) were less about comedy and more about giving serious reactions and opinions on what they are shown. Since then, the episodes have become more focused on the guys having funny reactions.
Large Ham: Depending on the episode, people like Race, Saberspark, BlackGryph0n, and Tombstone act like this.
Orchestral Design and Solrac, however, are always like this.
The Last of These Is Not Like the Others: In the Cold Open for the season 3 premiere reaction episode, everyone is talking about the new episode and how they've been waiting for it...and then cut to Race, who's looking at the camera and commenting how he needs a haircut.
Solrac does this during the episode break in the season 4 finale.
Mood Whiplash: The first several episodes are rather lighthearted...and then, for Halloween, we get the guys reacting to Cupcakes.
In the reaction to the season 2 finale, the cast act their usual funny, snarky selves...then, Twilight starts singing her sad reprise of "B.B.B.F.F.", and everyone becomes much more solemn.
And then directly after the above, when Chrysalis - disguised as Cadence - steps in, Race is smiling, thinking she's going to comfort Twilight. Then when Cadence's horn glows and she starts surrounding Twilight in fire, he gets an Oh, Crap look on his face, followed by a scream.
Ninja: BlackGryph0n dresses up as (and acts like) one during Bronies React to Cupcakes.
No Indoor Voice: Solrac's very shouty, to say the least. Justified, as he's known for that in the brony fandom.
Rated M for Manly: Dusty has a reputation for being the "Manliest Brony in the World."
Real Men Wear Pink: Among the bronies appearing in this series are Dusty, who is nicknamed "The Manliest Brony in the World", and BlackGryph0n and Robbob, both of whom are in the military. Gryph0n, in fact, often records his footage while wearing his fatigues.
Lampshaded by Robbob in the beginning of the season 3 premiere reaction...
Robbob: (walking into a room wearing his full military gear) Well, just got done saving America. Time to watch some ponies!
Running Gag: "I bet Luna's gonna have a really big role in this episode!"
Sarcasm Failure: In the first episode, when one of the teens in the Teens React episode they're reacting to uses "on the other side of the street" as a euphemism for "gay" (and basically calls bronies gay in the process), practically everyone in Bronies React is unable to do anything except glare at the camera or just make a "what the hell" expression with their face. D.Notive is the only one who responds to question the use of the phrase.
Vomit Discretion Shot: Bronies React to Cupcakes; Saberspark does not like it. He has trouble just talking after the first few minutes.
We Are Experiencing Technical Difficulties: In the reaction to the season 2 finale, when the first episode ends and the credits start to roll, Orchestral Design runs off to get a drink. Cue a "Please Stand By" screen.
Yanks with Tanks: BlackGryph0n is a member of the US Navy and has appeared in uniform in several videos.
