まじそれ

• 読み: まじそれ
• ローマ字: maji sore
• 発音: /ma.dʑi.so.ɾe/

意味

Seriously that — a short phrase expressing strong agreement, equivalent to 'couldn't agree more' or 'literally this.'

A combination of まじ (seriously/really) and それ (that), まじそれ is a quick, emphatic way to agree with someone's statement. It implies what the other person said is so accurate or relatable that no further elaboration is needed. Extremely common in LINE group chats and Twitter/X replies, often standing alone as a complete response. The variant まじそれな (with sentence-final な) adds extra emphasis.

例文

1. 「月曜って何であんなだるいんだろ」「まじそれ」

3. 「推しが尊い」「まじそれ！！」
