Sounds transcribed from Cyrillic laughter like hahaha have circulated for years in Russian speaking online communities as text slang for laughing, equivalent to English lol or haha. Short laugh clips using this spelling spread on soundboards and in meme edits because the repeated ha syllables are instantly understood across languages. This version is used less as a natural laugh and more as a stylised reaction effect, valued for its brevity and for signalling over the top amusement in chats, streams and short videos.
