superman is generally pretty good about having good posture and
maintaining his broadcast english but when he’s not careful clark has a
tendency to get a l’il bit drawly and hitch his thumbs in his pockets/belt/whateversometimes when he’s thinking he gnaws on his lip and drums on his hipbones and it’s very upsetting to watch quite frankly, what the hell clark, that’s not fair
he owns a lot of bootleg superman shirts because he thinks it’s funny but doesn’t wear them outside the house
the first time he bought eggs from the store he completely fucking smashed an egg to fucking pieces and freaked out because he thought maybe he didn’t know his own strength and ma had to tell him to find a fucking farmer’s market and get some real eggs. it took like twenty minutes on the phone to convince him that everyone who’s used to farm fresh eggs does that. your powers are fine, clark. those eggshells are just weak.
he is generally very careful about being a respectable role model as superman so he likes it when it’s just him and diana and bruce on missions because they know who he is and he can loosen up and act like a fucking dork.
he’s very vigilant about his dental hygiene because he doesn’t know if it’s even possible for him to get a cavity but WHAT THE FUCK WOULD HE EVEN DO IF IT WAS. HOW COULD HE EVEN GET IT FILLED. CAN YOU IMAGINE.
sometimes as a gag batman will shove superman’s shoulder and superman will tip over but one time batman does it near a canyon and not only does superman go along with it, he pretends to fall in and makes the ‘goofy falling off a cliff’ noise when he does it and batman nearly hurts himself trying not to laugh and he’s so fucking pissed that joke was so dumb goddamn it clark go fuck yourself
