buzz about

Hi what does buzz about mean as in:

“What is everyone buzzing about?”

Many thanks

More context would help, but probably it means “What is everyone excited about?”, or “What is everyone excitedly discussing?”, or something like that.

An additional point:
Changing the question by using ‘why’ instead of ‘what’ leads to a change in meaning
Why is everyone buzzing about?’ means ‘why is everyone running around excitedly from one place to another to another?’ (moving in a similar way to bees when they are collecting nectar).

Many thanks
That was really helpful.
