ガチンコ

• 読み: ガチンコ
• ローマ字: gachinko
• 発音: /ɡa.tɕiɴ.ko/

意味

Dead serious, no-holds-barred, or for real — describes something done with full effort and no pretence.

ガチンコ comes from sumo wrestling and describes a bout where both wrestlers fight with genuine effort — no match-fixing or holding back. In everyday slang, it means doing something with complete seriousness and maximum effort. A ガチンコ勝負 is a real showdown. The shorter form ガチ (gachi) is even more common in modern usage and has the same meaning.

例文

1. 今回はガチンコ勝負だから手加減なしで行くぞ。
2. あの二人のガチンコ対決は見ものだったよ。
3. ガチンコで相撲取ったら絶対あいつには勝てない。

避ける言い方

• フォーマルな場で「ガチンコで取り組みます」は砕けすぎ (Saying 'I'll tackle this gachinko-style' in formal settings is too rough — use 本気で or 真剣に)

起源と歴史

From sumo wrestling terminology: ガチンコ describes the sound of two wrestlers' heads colliding in a genuine, unscripted bout (as opposed to 八百長, a fixed match). The word was popularised further by the TV show ガチンコ! (1999-2003) and has since become standard slang for anything done seriously.
