What does SMT mean from a girl?

Could you please elaborate on the meaning of "SMT" when used in the context of a girl's statement or reference? I'm curious to understand if it's an acronym, slang, or a term specific to a particular community or subculture. Is it commonly used in the cryptocurrency or finance world, or is it more prevalent in social media, texting, or another domain? Clarifying the context and intended audience would help me provide a more precise explanation.
