So, imagine you have a big box filled with a bunch of small toys that are all different shapes and sizes. A globular set is when you take a special kind of toy from the box and you put it in a special group all by itself called a "globular set". It's like taking all the green toys and putting them in a separate box just for the green toys.
Now, this special toy in the globular set has some other special properties too. It's kind of like a big ball with a bunch of little balls stuck onto it. And the big ball part is called the "base" while the little balls are called "points".
So, to sum it up, a globular set is like taking a special toy from a box and putting it in a special group all by itself, and that toy looks like a big ball covered in little balls.
