Diu lei lo mo, also searched as diu nei lo mo, is a vulgar Cantonese phrase roughly meaning a strong insult aimed at someone's mother, which is why it is used purely as an angry outburst. The clip became a staple in Counter-Strike: Global Offensive lobbies and edits, where short voice shouts are replayed for comic rage. It spread through soundboards and gaming videos as a quick way to signal tilt without explaining the joke, and remains popular because the shout is recognisable even outside Cantonese-speaking communities.
