"Don't say it like that, you idiot," Kaiba grouses, not even caring that he's insulting Yuugi. He has every right to insult Yuugi right now! Woe to any man who tries to correct him on that, up to and including his brother!

"I bit him and he gushed like a goddamned oil derrick, what was I meant to do?"

Mokuba does a very adult thing, and pinches the bridge of his nose...before dragging his hand partway down his face. They're both idiots. Absolute idiots. This was supposed to be a super cool sleepover!

Spitefully, Mokuba parrots his brother's words:

"Language."
