omg he would do that. Bakugo is petty enough to piss on the floor just to spite Midoriya and watch him clean it up for him. Midoriya is unphased. Since Bakugo is playing along as a doggy he knows he won’t use his hands like humans do, so he will grab him by the neck and push his face into the puddle.
He does it very calm and almost gentle because he’s nobody that gets aggressive, really. “Bad pup. You’re old enough to know better.”
Bakugo is. Horrified. He can’t believe what’s happening.
