Funny story of 草 (くさ)
The other day, my boyfriend’s sister sent this sticker to his dad on LINE.
Because 草 sounds like 操 in Mandarin, which is a curse word. His dad was very confused why he got cursed.
The more I look at it, it seems to be ridiculing me for some reason.
嘲笑 (ちょうしょう) – ridicule

Anyways 草 means rofl, since www means lol, and how it became:
- 笑う (warau) → (笑) → w
- Multiple “w"s (wwwww) began being used to show stronger laughter
- The repeated "w"s visually resembled grass, leading to the use of 草 (kusa)
