Wait'll they get into talking about their worlds and heroes. Because Bakugo's not someone who's shied away from using his Quirk even outside his costume. Technically he's not supposed to, but even the golden child (with a major attitude problem) has some vices.

Bakugo's guilty of actions over words, assuming chucking a whole box at someone would indicate it's theirs. When the other guy asks about a light, the spiky-haired blonde lights another sparkler and then tosses it to Peter, fully expecting him to catch the unlit end. You know, rather than get up and move over there like a decent human being...

"Haa?! They wanna enforce a fucking nudist colony ruling?!" That's fucked up! If someone comes after his clothes, they're going to get off way worse than the shitty seagull lifeguards he blew up on the beach. "Screw that!" No one's gonna force him to do anything! Even if he's salty as hell about getting kidnapped again...
