厨

• Reading: ちゅう
• Romaji: chū
• Kanji breakdown: 厨 (kitchen) — used as phonetic substitute for 中 (middle) from 中坊 (middle schooler). The kitchen kanji is purely a homophonic pun, not semantic.
• Pronunciation: /tɕɯː/

Meaning

Suffix meaning annoying fanatic or obsessive person — added to topics to mock someone's over-the-top enthusiasm.

厨 originated on 2ch (now 5ch) as a derogatory suffix implying someone is as immature as a 中学生 (middle schooler) about their obsession. 厨 is added to any topic: 信者厨 (blind follower), 嫌儲厨 (anti-profit obsessive), ゲーム厨 (gaming addict). While harsh, it is commonly used in internet arguments to dismiss opponents as irrational fanatics.

Examples

1. あいつ完全にApple厨だから何言っても無駄だよ。 He's a total Apple fanatic so there's no point arguing with him.
2. 厨って言われるくらいハマってるってことでしょ。 Being called a 厨 just means you're that into it, right?
3. ネットで厨認定されると何言っても聞いてもらえない。 Once you get labeled a 厨 online, nobody listens to anything you say.

Do Say

Don't Say

• 面識のある人に「厨」と呼ぶのはネットスラングすぎて失礼 (Calling someone you know in person a 厨 is too internet-slangy and rude)

Common Mistakes

• Not realising the kanji 厨 (kitchen) is purely a phonetic pun, not meaningful — the actual meaning derives from 中 (middle school)
