1軍

• 読み: いちぐん
• ローマ字: ichi gun
• 漢字の分解: 1 (first) + 軍 (army/team) → first string, top tier
• 発音: /i.tɕi ɡɯɴ/

意味

The top-tier popular kids in a school's social hierarchy; the 'first string' of the social pecking order.

1軍 originally refers to the first-string team in sports (especially baseball), but in school slang it means the most popular, socially dominant group of students. They tend to be outgoing, fashionable, and often athletic. The hierarchy extends down to 2軍 (second tier) and 3軍 (lowest tier). Being 1軍 often determines seating arrangements, group dynamics, and who gets attention at school events.

例文

1. あのグループは完全に1軍だから、近寄りがたいよね。
2. 1軍の連中はいつも教室の真ん中で盛り上がってる。
3. 高校では1軍じゃなかったけど、大学デビューしたよ。

正しい言い方

• 1軍の人たちって自然にモテるよね。 (The top-tier kids are just naturally popular.)
• 俺は2軍だったからそんなイベント知らないわ。 (I was second-tier so I didn't know about those events.)

避ける言い方

• 「お前は3軍だろ」は相手を傷つける (Telling someone 'you're third tier' is hurtful — use cautiously even as a joke)
