The phrase comes from everyday French slang, where un mytho describes someone known for making things up or stretching the truth for effect. Online, the short Hakimi-labelled clip spread through French meme pages, group chats and short video edits as a ready made reaction for dubious claims. Its brevity helped it travel, since it can be dropped over almost any clip without explanation. It remains popular because the accusation is understood instantly in French speaking communities, while the sharp delivery still reads as funny even to viewers who only catch the tone.
