…The size difference does not bode well.

Then they fuck.

Hahah!

Oh shit, I thought that was Scootaloo.

@Scrounge  
Ha xD

Alternate interpretation: Big Mac isn’t being an overprotective big brother. He’s just annoyed that Taps is blocking the doorway.

You gonna die ( I have a sister and I was just like this when her first boyfriend came to take out on a date except I had my pistol on my side I may have overdone it but they were home at curfew I felt so bad for so long but she is my sister and A big brother has to look after his little sister)

@Scrounge  
Lol that would so happen. And Granny Smith comes out and is like: You best treat my little Apple Bloom right boy!

@darknessRising24  
I did it once. But now she’s 20

Ahhh. I can’t wait to do this to whatever little twerp dates my little sister.

@nuclear brony  
Yeah, I can just see it now. There’s Tender Taps, and there’s Big Mac towering over him, the poor kid feels the walls closing in as Big Mac looks him over… He’s expecting to be read the riot act, but all he gets is a casual “eeyup” before Big Mac just walks past him and returns his attention to what he was drinking before this little distraction.
 
Then Applejack comes out, and he tries to say hi to her… And she gives him a glare that would make Discord himself freeze dead in his tracks.

@Background Pony #8406  
Agreed. Makes for some funnies if you add in the idea that he’s just trolling. As a serious headcanon though? Nah.

“Overprotective Big Mac” is headcanon I dislike the most.
 
_{But no one cared}

Big Mac looks like a big, scary protective dude, but he’s always seemed like the kind who could let his sisters explore their lives and feelings. It’s Applejack who Tender Taps ought to be worried about.

This is how every suitor would see Big Mac, whether he intended it that way or not.
 
I imagine that this is from Tender’s perspective, with him freaking out when Big Mac answers the door. If this is when they’re basically high school age, then the relative sizes certainly point to that conclusion.

@ColdhardSilver  

 
I lol’d.

Big Mac: Ah hear you’re pretty quick with your hooves  
TT: Why yes I am, in fact…wait I mean no I’m not! NO I’M NOT!

Don’t crack under the pressure, boy, glare BACK.

@Outcast’s Redeemer  
perfect  

@RIG
 
After catching a glimpse of Big Macintosh’s small glare while Limestone threatened Apple Bloom in Hearthbreakers, I kinda have to disagree.
 
@Softy
 
Now that is intimidating.

Applauds

BP24F8 wins the thread.

Protective big brother mode: activated.

That line always hits me with a bit of Fridge Logic… If you’re in prison, doesn’t that leave your precious little girl relative at the mercy of any boy that comes around, since you’re not there to “protect” her anymore?

“Boy, I’ve got no problem going back to prison.”

Inside of Big Mac’s head
 
Anger starts shaking before he shouts “Red Alert!”  
Fear jumps before slamming down the big red button. Suddenly alarms blare out the word “BOY! BOY! BOY!”
 
Big Mac just sits there looking at Tender Taps, his face passive. But inside, anger was steaming. “I know what you’re doing here Tender. You don’t think I know but I know you little punk!”
 
“He’s not good enough for Apple Bloom! NO ONE IS!” Fear screamed.
 
Sadness shouted his own two cents in, “Go Back to jail!”
 
Anger watched at the smaller pony looked around the entry way to the house. “What are you looking for Tender Taps? Something to steal?”
 
“Like our sister!?” Sadness yelled out.
 
“Should we say somethin?’” fear asked.
 
Anger held out his hoof and said, “No, he’d be expecting that. Give him the silent treatment. He’s about to crack… Ah’ can feel it.” On the outside Big Mac’s left eye twitched as he went into silent mode. Not even his breathing was audible.
 
Tender Taps however was too busy in his own mind to notice. His own emotions were doing whatever they did normally. Big Mac allowed his chest to rise a little, pulling his shoulders back and allowing his quiet yet deadly stair to do it’s work, hoping that it would be enough. Slowly Tender looked up at Big Mac’s massive form.
 
Inside Tender’s mind fear looked up at the monitor. “Hey, what is he looking at?” he asked aloud.
 
“Happy turned to him laughing, “Probably your dumb tie!” he said before tugging on it.
 
Fear threw down his drink and tackled happy. Meanwhile Disgust, who was dancing, laughed at their antics before he crashed into something and caused many of the memory balls to fly every which way.
 
On the outside Tender Taps let out a small chuckle. Big Mac’s eyes grew wide.
 
Back inside the jolly red giant’s head Anger was growing more angry. Fear looked up with worry “Sir, Intimidation is failing!”
 
“Bahh!” Anger shouted with a throw of a hoof,” Increase the pressure! engage!”
 
On the outside Big Mac took a breath, “So, Tender Taps, What d’ ya’ like t’ do… fer’ fun?” Macintosh said aloud, his deep voice causing the smaller colt to look at him.”
 
Tender shrugged before replying, “I don’t know… Stuff?”
 
Big Mac’s eyes twitched. Inside anger looked back to fear, “That’s it he’s out of here! Prepare the Boot!”
 
“Preparing the boot Sir!” fear shouted before he and sadness took out keys and plugged them in. “Waiting for your orders Sir!” Fear continued.
 
“I like to dance…” Tender continued.
 
Anger stopped before remembering back to his colt years “We danced.” fear pulled up a memory of a younger Macintosh dancing to a headbanging song.”
 
Big Mac smiled, “ Ah’ danced. First place in my school’s talent show.”
 
Tender smiled, “Cool. I dance professional gigs. A lot of ballet…”
 
“But, Me and my friends/Dad like to dance to a lot of harder music like AC DC,” They said at the same time. They both looked at each other. Tender said the first thing that came to his mind. “Whaaat?”
 
Upstairs Apple Bloom looked in shock to her big sister, “Ya’ left Tender Taps with Big Mac? Applejack this is so embarrassing!”
 
Applejack scoffed. “Apple Bloom, Yer’ brother would never do anything to upset y-” She began only to get interrupted by a loud scream followed by hevey metal. Her eyes flew open as she remembered Big Mac’s past.
 
Downstairs Apple Bloom stopped at the stairs and looked at the scene before her. Tender and Big mac were dancing. Granted Tender was more professional than the bucking bronko that Big Mac was. Both of them were laughing and halving a good time.
 
A few moments later Apple Bloom ran tugging along Tender as they went on their date. Big Mac smiled as he watched the two leave. “He’s a nice colt…” He turned to Applejack. “I guess ah’ll get the shovel… Too bad too Ah really liked him.” He said before turning into the house.
 
Applejack laughed as she followed him inside before closing the door.
