I explained how keyboard smashing in English expresses laughing really hard and she taught me the Japanese equivalent in return!!
As some of you might know, in Japanese, “w” from the word “to laugh” 笑う 「わらう」 is basically like “lol” in Japanese so when there’s a bunch of “w”’s together it looks like this wwwwwwwwwwwwwwwwwwwwww
and it looks like a bunch of grass so one slang word to show something is funny is 草 「くさ」 which is the word/kanji for grass so you don’t have to type out a bunch of w’s.
So the step up from 草 is 大草原 「だいそうげん」 which means prairie since there’s a lot more grass.
And if something leaves you laughing so much that you can’t hold it back you could say 大草原不可避 「だいそうげんふかひ」 which basically means “inevitable prairie”.
The “inevitable part”, 不可避 「ふかひ」 in this phrase means laughter is inevitable and you can’t help but laugh.
