Imagine you are going to a friend's house to play, but before you can go in, your friend's mom asks you to read and sign a piece of paper. The paper says that you promise to be nice and not break anything while you are there.
This is kind of like a browse wrap! When you go to a website, there might be some rules that you have to agree to before you can use the website. These rules are usually written in a little box or link that is somewhere on the website.
If you click on the box or link, you can read the rules that you have to follow. It might say things like "you can't use this website to do anything bad" or "you promise to give us your email address." These rules are called the "terms of service."
When you use the website, you are agreeing to follow these rules, just like when you sign the paper at your friend's house. But with browse wrap, you don't actually have to sign anything or say "yes, I agree." Just by using the website, you are telling the website that you agree to the rules.
