The word laughter 笑い - warai" got shortened to "www" which kinda looks like grass. Therefore "grass" means "lol"

romaji for a japanese kanji meaning grass, used in a similar manner to "lol", "lmao", "rofl", keymashing is some cases, or "www" (the last one of these being the very source of kusa's use due to the w's "resembling grass"). primarily used in communities with strong, notorious ties to or heavily driven by japan but that also count with a western following.
*in response to Kureiji Ollie simping for any other hololive talent*
Half the chat when Ollie inevitably gets rejected: KUSA

The slang for LOL in Japanese, it also means "grass".

Mostly used on Japanese comment sections and livestreams when something funny happens.
Guy 1: So I was on the Internet last night watching Japanese livestreams,

Guy 2: And?

Guy 1: Something funny had happened, and when that happened, everyone had typed 草 (Kusa), and I at first didn't know what that meant, but I later on learned that it mean "LOL".
