The letter S has another definition, meaning "seconds kill", which is a term often used by gamers. If a gamer is very strong and can easily beat his opponent, then he may use his signature S to show his great strength, which can also be his symbol. However, it should be noted that only truly powerful people can use this personalized signature.
In addition, the letter S has different meanings in different cultural backgrounds. For example, in western culture, the letter S can represent a type of personality, which is called "S-type personality". People with this personality have the characteristics of strong self-assertion, strong decisiveness and strong sense of purpose. In Japanese culture, s is also considered as sex addiction, which stands for "abuse" and is related to personal sexual orientation. Therefore, when using personalized signature, we need to think according to the specific cultural background.
