捨て垢

• Reading: すてあか
• Romaji: sute aka
• Kanji breakdown: 捨て (throwaway/disposable) + 垢 (internet slang for account/アカウント) → disposable account
• Pronunciation: /su.te.a.ka/

Meaning

Throwaway account, burner account — a disposable social media account not linked to one's real identity.

Combining 捨て (disposable/throwaway) with 垢 (internet slang for アカウント/account, derived from the slang reading of 垢 as 'aka'), 捨て垢 refers to temporary or anonymous accounts created for specific purposes. People use them for anonymous posting, following accounts they do not want on their main profile, or participating in online discussions without revealing their identity.

Examples

1. 本音は捨て垢でしか言えないわ。 I can only say what I really think on a burner account.
2. 捨て垢で推しの情報だけ追ってる。 I use a throwaway account just to follow updates about my favorite idol.
3. 炎上しそうなこと言うときは捨て垢使う人多いよね。 A lot of people use burner accounts when they want to say something that might cause drama.
