A lot of excited noise, attention, or fuss about something, sometimes exaggerated or unnecessary.
Origin unclear but possibly from 'hoop-la' (a carnival game where you throw rings at objects). First recorded in American English around 1884, it may derive from excitement of the carnival game itself.
The carnival game connection is perfect—hoopla describes that same breathless excitement and sometimes false promises of winning that carnivals and hype culture thrive on!
