草 (kusa) = lol in japanese chat rooms : r LearnJapanese - Reddit Eventually that got shortened to simply 'w' and was often repeated as 'wwwwww' to represent continuous or emphasised laughter Multiple w's in a row was interpreted visually as blades of grass and thus in reference to this 草生えた【くさはえた】 (lit 'grass has grown') emerged as a new variant
What does wwwwwwwwwwwwwwwwwwwwwwww mean : r NoStupidQuestions - Reddit It's an emoticon that's just being used a whole bunch at once - the W is the mouth of the face a kind of grumbly, lazy or kind of cute face -w- is another one also using the w as a mouth If it's actually korean it's GG (good game)
