Thanks to the Internet, we have an endless amount of knowledge at our fingertips. But there are some things out there that even the Internet can't help us to learn about. That includes things such as the "cool S," that silly symbol you doodled all over your school books. Even though people have tried to find its meaning, this is all we know about it.
There are many people who have theories about the origins of the S, but most of them seem far-fetched. Some people think that it's a paranormal symbol used to attract forces from other realms. There are others that believe it's used for magical protection. Some people even think that the symbol is used for mind control since they think it's usually drawn after being told to do so. And it looks like people start drawing it at a specific age.
