Origin and Popularity of SMT

Where Did SMT Come From?

SMT became popular during the early days of mobile texting and instant messaging. When text messages had strict character limits, people shortened commonly used words to save space and time. “Something” was frequently used, so it naturally became abbreviated to SMT.
