Based on this absolute gem by @pretty-bratty. Please give their post some lovin. It's amazing. This fic is nowhere near as good as the original post, but here it is anyway.

Steve leaned on the Camaro's hood and lit up a smoke, chitchatting with Nancy and Jonathan while waiting for Billy to join them. The sun danced down upon them and Steve soaked it in. His spirits were high, riding on the trail of a great day. Though, it was mostly from English class that day. Billy had written him something lovely.
Billy came stomping up to them, huffing and grumbling to himself. Something must have happened to put him in such a mood. He pushed himself off the hood and stuck out his arms to embrace Billy.
"Can I speak to you, Harrington? In private?" Billy grunted.
Still giddy from the last few hours, Steve looked over at Nancy and Jonathan. "Ooo, someone's in trouble!" he said in a sing-song voice.
They looked back at him with grave expressions. Steve glanced at Billy, who was damn near fuming. Oh God, what did he do this time?
"Yeah, it's me," Steve said, defeated. "I don't know why I did that."
He and Billy climbed into the Camaro for some privacy. As soon as the doors were closed, Billy turned to him, eyes wide.
"What the fuck did you say to Tommy?"
Steve wracked his brain to try and remember when he'd spoken to Tommy. "You mean during English class?" Billy glared at him until Steve continued. "He was complaining about not understanding im- abnic - ambic penta-"
"Iambic pentameter," Billy cut in.
"Yeah, that. So I told him to ask you, cause you're like... A professional at this poetry shit. Like, you're really fucking good, man."
Billy pulled the cigarette from Steve's mouth and took a drag. "You ever think that, I don't know, I don't want people to know I write poetry?"
Steve shrugged. "But it's really beautiful. I was complimenting you."
"So you told Tommy, of all people."
Steve sighed. "So what?"
"Poetry's lame."
"It's not lame. Stop being a brat!"
Billy whipped his head toward Steve. "Me? I'm being a brat?"
"Yeah," Steve said and shoved Billy's shoulder. "You are."
Billy shoved him back. Steve did it again. Again, Billy returned the gesture, until they were having a cat fight in the front of Billy's car, shoving and slapping at each other, but not actually accomplishing anything.
Outside, Nancy gave Jonathan a look. "Should we just... Go?"
Jonathan nodded. "That's probably for the best."
