What it means
Zany is for someone or something wildly silly, hyper, and entertaining in a harmless way. Not sinister, not properly unhinged, just running on cartoon-goblin energy and loving every second of it. You hear it for chaotic comedy, daft behaviour, or anything so goofy it feels one step away from a pratfall.
Usage examples

Where it comes from
It comes from Italian zanni, the stock comic servant from commedia dell’arte. English picked it up in the 1500s through theatre talk, where a zany was the clownish sidekick doing exaggerated nonsense. Later it stretched into the everyday adjective for playful, madcap, high-energy silliness.
