Here are some quotes I've gathered from various episodes of Kodocha. :) More coming eventually.
"DANGIT! This really pisses me off!! I can't stand this! Why me!?! Why me? Ever since 6th grade started, life there has been HELL!! I CAN'T STAND IT! Oh my GOD, it just SUCKS! LIFE sucks! My whole life sucks! Why can't it be a little more like those nice shoujo manga? But NOOO! I have to have SATAN for a schoolmate!"
"That's not a school, it's a ZOO! Those aren't boys, they're monkeys! BABOONS! Dirty, smelly, stinky, butt-sniffing baboons!"
"Hey, Hayama! Yeah, I'm talking to you, Astroturf-for-brains! Are you listening to me!? 6th grade student #36 Hayama Akito! YOU YOU YOU YOU! It's ALL YOUR FAULT! I come to school everyday and all I get is crap thrown by you and your little monkeys! What the hell is wrong with you!?"
"That blowhard is so chicken.. he couldn't pick his nose without help!"
"Why don't you guys look in the mirror and see what it looks like to have NO brains at all! Even monkeys look smarter than you guys!"
"Look, we're not children anymore, so why don't we split our butts?"
"Hayama! You broke the promise. You liar liar liar liar liar!! Now EVERYONE'S going to know what Mr. Happy looks like!!"
"You're afraid of the.. naked fun!"
"Go kill yourself, why don't you! I'm not gonna stop you! Go smash your head on a brick of tofu and die!"
"I don't have a clue about how you feel. That's why I wanted to understand you and help you."
"I'm genki genki monkey monkey lucky lucky!"
"Wait and see, Hayama. I'm gonna make you crack a smile yet, because life is fun."
"You two are IDIOTS! How can you let an elementary school boy go out to dinner alone? It's because of you that Hayama did such bad things in school.. like picking on the kids and the teachers. You can him a devil's child, but what about you? Idiots. I'll call it 'Oyakodon-baka'!"
"Aa-chan. You're such an interesting child with juice coming out of your nose."
"Hey wow, I'm like a shoujo manga heroine! I'll fling flower petals!"
"What are you doing farting in the morning, Hayama?"
"Ahh!! A freshly hard-boiled Sana-chan! This and that and everything is to be blamed on YOU, HAYAMA!"
"Oh, the baby chicken. It's the same as the baby chicken. Aono-chan's egg won't come back. The chicken, the lie that lets children dream. Rei-kun.. gave me a chicken too. That's what it's about. I wonder, when one day Aono-chan realizes her mistake.. will she be as humiliated as I am?"
"It sucks to be humiliated, but it would suck even more to have never seen Rei-kun!"
"Mama said this wasn't a real love.. but I think Rei-kun was my first love. I want to keep thinking that this was really real. If I think that, that'll be true always, won't it? That's okay, isn't it?"
"I'm not breathless enough to be kind to a man I've broken up with." (she means lifeless)
"I don't know what to do. Hayama and I, who usually talk as if we were the only ones in the world, are children after all. We're half-servings. Interesting line.. In times like this, what do we do without an adult?"
