Kusa (Online Laughing / Grass Slang)
"Kusa" (草 - literally "Grass") is a standard Japanese internet slang used to express laughter or amusement. Equivalent to "lol" or "lmao" in English, it has become a staple of modern Japanese digital communications.
- Origin from "w": In Japan, "w" (abbreviation of warai, meaning laugh) is typed repeatedly to show amusement. When typed as "www", it visually resembles blades of grass growing out of the screen.
- Scales of Humor: Depending on the hilarity, the expression evolves from "Kusa" (basic grass) to "Daisougen" (big meadow/prairie) or "Kusa koete mori" (beyond grass to forest).
- Verbal Adaptation: Younger generations use it in spoken, real-life conversations as well, saying "Kusa haeru" (grass is growing) to mean "that's funny."
The Evolution from "(笑)" to "Kusa"
Historically, Japanese netizens typed "(笑)" to indicate laughter. Over time, gamers and online forum users shortened this to "w" for faster typing. The visual association of the characters "www" with lawn weeds led to the coining of the verb "Kusa-haeru" (to grow grass), which was eventually shortened to the noun "Kusa" (grass) itself.
Typical Dialogues and Scenarios
Friend A: "I walked all the way to school today only to realize it's Sunday."
Friend B: "Absolute Kusa. Did you at least get exercise?"
FAQ
Q: Can I use "Kusa" in business emails or Slack channels?A: No. Since it is highly informal street slang, using it in professional settings is considered unprofessional and disrespectful. Use standard expressions like "面白いですね" (That is interesting) or "感銘を受けました" instead.
Etiquette: Avoid Mockeries
While "Kusa" is casual and easy to use, it can sometimes carry a mocking or sarcastic undertone depending on the context. Never reply with "Kusa" when someone is expressing genuine worry or reporting a serious issue, as it may feel dismissive and rude.
