A whiz is someone or something that is extremely good at something.
When we say someone is a whiz, we usually mean they're really talented or skilled at doing a particular thing. Maybe they can cook like a pro, fix cars super fast, or even do math in their head without any trouble! It's not just about being good, it's about being exceptional – the best of the best. For example, if your friend is a whiz with video games, you might know exactly who to call when you need help beating that one level. The word "whiz" can also be used to describe something as exciting or impressive, like "That fireworks show was a real whiz!"
To make a whirring or hissing sound, similar to that of an object speeding through the air.
