What does "[noun] + buzz" mean?

Good question! "Buzz" is actually a noun here too, referring to an atmosphere of excitement, anticipation, or activity. Here, it's actually "Olympic" that modifies "buzz." Thus, you can think of "Olympic buzz" as meaning the atmosphere of anticipation surrounding the Olympics. Ex: What's the buzz in business recently? Ex: I don't understand the street fashion buzz.
