So we’ve had using Bakugou as a meme or as a verb, but now think about this – using the word Bakugou for a whole language.
Like, one day, when Bakugou is at it again, swearing left and right for now visible reason. The others don’t really react to him, knowing him to well to be faced by his behavior. And as long as he is not insulting them directly, that means that he is not really angry at one of them, so it’s fine.
Until Sero comes back into the room, having left before Bakugou had started, and startles a bit at the sight in front of him. Turning to Shouto, the only one who seems to really listen to what Bakugou is saying, he asks, “What’s got him riled up this time?”
“I don’t really know.”
“Huh? He didn’t say anything?”
“Well, I suppose he did,” Shouto shrugs, “But I don’t speak Bakugou.”
Suddenly, everyone who had pretended to not listen up until now looks up, giving up on their façade of impassiveness, and everyone asks at once, “What?!”
Well, not everyone. Shouto blinks, startled at the sudden attention. Bakugou goes silent, staring wide-eyed at the other boy. And Izuku had choked on his water and is now coughing into his palm.
“Did I say something funny?” Shouto frowns slightly, looking from one to the other. Especially the still coughing Izuku receives a worried gaze.
“Did you just turn my name into a freaking language?!” Bakugou asks, quietly, so incredulous that he doesn’t even yell.
Izuku’s coughing takes on a whole new quality. It’s not a bad thing, though – Shouto relaxes, realizing that his friend is not dying over there, but instead stifling his laughter, shaking with mirth.
Before Bakugou can overcome his initial surprise, his classmates already pick up this chance.
Kirishima starts grinning from ear to ear, showing off uncanny sharp teeth and gleaming eyes. “That’s brilliant!”
Bakugou whirls towards him, expression morphing from surprise into something akin to shocked anger. “Hair for Brain, I’m freaking warning you….!”
“Bakugou has his own language!” Kirishima continues without a care in the world. “That’s so true!”
“You mean his swearing?” Momo wants to know. “How is that a language?”
“It’s about how he uses the swearing, I think,” Kaminari chimes in, tapping his chin in thought. “Like, he doesn’t use the swear words in their original sense – there is more meaning behind it.”
“Yeah!” Now it’s Mina who has picked up, all for it. “Remember when he told us that we are useless and then did the work all himself? “Useless” actually means that we shouldn’t bother with something that we can’t do when he is there to do it for us!”
“Oh, I never thought of it that way.”
“Or the dead threats! He only uses those when he is embarrassed or touched…”
“… but can’t show it and then he insults us?”
“Could you all shut up, you damn morons?!” Bakugou had finally managed to find his voice again, and that in quite a volume. “There is no such thing as my language, you idiots!”
His classmates go silent, interrupted in their musings, and look over at him, gazes curious and contemplating.
As they start smiling, Bakugou suddenly regrets saying anything.
“So when useless means don’t bother…”, Mina starts, smile turning into a smirk.
Kaminari joins her all too happily, grin mischievous. “…and death threats are to cover something up, then insulting us means probably…”
It is Kirishima who finishes, sing-song voice and all, “Insults means that he loves us!”
And Bakugou all but explodes. He surges forward with loud swearing, catapulted forward by his stuttering explosions – indicating that he is not really in charge of his emotions right now.
He misses Kaminari, who dodges with a jump, and Kirishima, who rolls out from under his explosive friend.
Suddenly, everyone is laughing, screaming, and scrambling to get away from Bakugou, who hollers after them: “COME BACK HERE, YOU GODDAMN PESTS!”
“He loves us so much, guys – whoa!“ Sero laughs before he dives away with a startled yelp which turns into laughter as Bakugou’s grapping hand misses him, too.
“We love you too, buddy!” Kirishima yells, happily, before he runs for his life.
“SHUT IT ALREADY!”
When Aizawa and Toshinori come running shortly later, worried by the screaming and sounds of explosions, they only see their students running around like crazy, sidestepping all the while as Bakugou chases them through the dorms, swearing and yelling.
Only Izuku, Uraraka, Tsuyu, Shouto, Kouda and Iida have somehow managed to stay out of it.
“…Do I even want to know it?” Aizawa addresses them.
“Probably not, Sensei,” Izuku answers, honestly.
Aizawa considers that for a moment, checks again – Bakugou is not really hurting anyone, not even really trying – and then nods. “Fine.”
And he walks away as if nothing happened.
Toshinori stays to watch, torn between amusement and slight worry. “Do I want to know it?”
His students exchange gazes, considering. Shouto mumbles something that sounds like “Shouldn’t have said that?” but Izuku laughs and pats his back reassuringly.
“Did you know Sensei?” Uraraka is the one to start talking, smiling brightly. “Bakugou-kun has his very own language!”
“Really? Now that sounds interesting…”
Basically, Bakugou never gets out of this ever again. Whenever he starts swearing loudly, his classmates smile so knowingly and almost fond, that Bakugou almost swallows his tongue the first few times this happens.
(He would never admit that he gets used to it over time.)
