What does mega popular mean?

Excuse me, could you please clarify what you mean by "mega popular"? I'm not entirely sure of the context in which this phrase is being used, but typically, when we say something is "mega popular," we're referring to its immense popularity or widespread appeal. It's a way to emphasize just how widely recognized or beloved something is. Could you provide a bit more context or an example of where you've encountered this phrase? That might help me give a more specific and accurate explanation.
