The original recording behind Lem Lem is not clearly documented, and no confirmed source work, performer or year is attached to this clip. It circulates mainly as a short soundboard file, shared for its repeated lem lem hook rather than any scene it came from. That lack of context helped it become flexible online, where creators lift the chant into meme edits, reaction posts and short videos as a standalone joke. It stays in use because the phrase is easy to recognise, easy to loop and works without explanation.
