Khaby Lame, a Senegalese creator based in Italy, became one of TikTok's most followed accounts in 2021 by silently reacting to pointless life hacks without saying a word. Fans began reusing short mechanical and looping audios under his clips to underline the contrast between elaborate hacks and obvious answers. This mechanism version spread through reposts, edits and soundboards as shorthand for that format, and it remains popular because the gesture and the joke translate instantly across languages, even without the original video playing.
