Not as good as you say with 口でいうほど〜ない

In a classroom, Genta, Mitsuhiko, and Ayumi crowd around Conan's desk while other classmates chat behind them. Conan, holding a book, turns to look at them.
名探偵コナン » Volume 6 » Page 92

At Teitan Elementary, Genta asks Conan whether the thing he promised them should be ready by now.

コナン:
「アレって?」
“What thing?”
元太(げんた):
「なんだオメー ゲーセンでの約束(やくそく)忘(わす)れたのかよ?」
“What, you forgot the promise you made at the arcade?”
光彦(みつひこ):
「ホラ! 君(きみ)がいったじゃないですか! このゲームでオレに勝(か)てたらなんでも作(つく)ってやるって…」
“Come on! You said it yourself! 'If you can beat me at this game, I'll make you anything you want...'”
歩美(あゆみ):
「そうそう、コナン君(くん)、口(くち)でいうほど強(つよ)くないんだもん…」
“That's right. Because you're not as good as you said you were, Conan...”

Key Points

1口(くち)でいうほど〜ない = “not as ~ as you say”
  • Aほど〜ない means “not as ~ as A”. Here A is a clause, 口(くち)でいう, “what you say”. Conan’s claim is the yardstick, and 強(つよ)くない says his real skill falls short of it.
  • 口(くち)で言(い)う is literally “to say with your mouth”. It contrasts words with what someone can actually do.
  • 強(つよ)い is “strong”, but for games and sports it means “good” or “hard to beat”.
2Giving a reason with 〜んだもん
  • もん comes from もの and gives a reason in a casual, childlike way. Ayumi backs up Mitsuhiko by explaining how they won: Conan wasn’t as good as he’d said.
3Reminding someone with 〜じゃないですか
  • 君(きみ)がいったじゃないですか is “you’re the one who said it!” Mitsuhiko uses じゃないですか to remind Conan of something he should already know. Mitsuhiko talks politely even to his friends.
  • The って at the end of his line quotes Conan’s promise: このゲームでオレに勝(か)てたらなんでも作(つく)ってやる.
4Doing a favor with 〜てやる
  • 作(つく)ってやる is “I’ll make it for you”. やる after a て-form says the speaker does something for someone of equal or lower standing. It sounds like Conan talking down to his classmates.
5Genta’s rough speech
  • オメー is a rough pronunciation of お前(まえ), “you”. 〜のかよ makes his question sound accusing: “You forgot, huh?”
  • ゲーセン is short for ゲームセンター, “arcade”.
