What does it mean for a man to suddenly sing Happy Birthday on the live broadcast?

The word Happy Birthday comes from the live game circle.

It was more than ten years ago. Brother Bao, the anchor of Dota2, always makes mistakes when explaining the game, so he is often sprayed. At that time, many water friends brushed "Happy Birthday to Brother Bao", which means pretending that today is Brother Bao's birthday and giving him face. His mistakes on his birthday can be forgiven. This stalk slowly began to catch fire in the game circle. Later, after the rise of the short video platform, this stalk also began to catch fire. Because of different circles, this word has a different meaning in many places.
