Ligangu circulated as a short sound on TikTok-style soundboards, where its name comes from the chant users hear and search for. With no clear lyric or credited source, the clip spread because it is easy to recognise, loop and drop into almost any short video. Its length makes it useful for edits that need a full arc of build and payoff in under fifteen seconds. It remains popular for meme compilations, reaction cuts and reposted edits where a familiar viral sound does the comedic work.
