Meaning

A Twitter addict who posts obsessively and spends excessive time on the platform.

A compound of ツイ (from ツイッター, Twitter) and 廃 (from 廃人, haijin, meaning 'ruined person' or 'addict'). ツイ廃 describes someone who tweets constantly, checks their timeline compulsively, and seems unable to stop using Twitter. It is often used self-deprecatingly — users jokingly call themselves ツイ廃 while acknowledging their unhealthy attachment to the platform. Despite Twitter's rebrand to X, the term persists.

Examples

  1. 1日100ツイートって完全にツイ廃じゃん。 100 tweets a day? You're totally a Twitter addict.
  2. ツイ廃すぎて寝る時間なくなってきた。 I'm such a Twitter addict that I'm running out of time to sleep.
  3. 友達にツイ廃認定されたけど否定できない。 My friend officially labeled me a Twitter addict and I can't even deny it.

Do Say

Don't Say

  • 他人を馬鹿にする意味で「ツイ廃」と呼ぶ (Don't call someone a ツイ廃 mockingly — it's typically used as affectionate teasing or self-deprecation)

  • Taking the 廃人 part too literally — ツイ廃 is usually used humorously, not as a serious diagnosis
