Hypertasking means trying to do a lot of things at the same time, like playing a video game while listening to music and talking to someone else. It's like you have lots of different tasks in your brain and you try to handle them all at once. It might seem like a good idea, but it can make your brain feel tired and it can be hard to focus on any one thing for very long. It's like trying to play with too many toys at the same time - you might have fun with all of them, but you won't be able to really enjoy any one toy as much as you could if you just played with it on its own.
