ガチで草

• 読み: ガチでくさ
• ローマ字: gachi de kusa
• 発音: /ɡa.tɕi de ku.sa/

意味

Genuinely hilarious — emphasising that you are actually laughing out loud, not just being polite or using 草 reflexively.

This phrase combines ガチで (seriously, for real) with 草 (internet slang for laughter, derived from ｗｗｗ resembling grass). While 草 alone has become so overused that it often just means mild amusement, adding ガチで signals authentic, uncontrollable laughter. It is the Japanese internet equivalent of 'I'm actually dying' — a way to cut through the noise and tell someone that this time, you really are laughing.

例文

1. 弟がケーキ顔面に落としたのガチで草だった。
2. あのゲーム実況者のリアクション、ガチで草すぎて電車で吹いた。
3. 今日のグループLINE見た？田中の自撮りガチで草。

使い方ガイド

場面: social media, texting, gaming, friends

トーン: amused, emphatic

正しい言い方

• さっきの動画ガチで草なんだけど見て。 (That video just now is genuinely hilarious, watch it.)
• ガチで草、涙出てきたｗｗｗ (Actually dying laughing, I'm tearing up lol)

避ける言い方

• 目上の人に「ガチで草ですね」は不適切 (Saying 'gachi de kusa desu ne' to a superior is inappropriate — pure internet slang has no polite register)

よくある間違い

• Overusing ガチで草 for everything — the whole point is that it signals genuine laughter, so using it constantly defeats the purpose
• Using it in spoken conversation with people unfamiliar with internet slang; it can sound very odd outside its native online context

起源と歴史

A natural evolution of Japanese internet humour. 草 (kusa, grass) comes from the visual resemblance of ｗｗｗ to blades of grass, where ｗ stands for 笑い (warai, laughter). As 草 became overused and lost impact, ガチで was prepended to restore emphasis.
