What is sm meaning in text?

The acronym "sm" most commonly stands for "sadomasochism" in text. It refers to a sexual practice in which one person derives pleasure from inflicting pain or humiliation on another person, who in turn derives pleasure from receiving it. The term has also been used more broadly to refer to relationships that involve domination and submission, although this is a related but different concept. The use of this term in text should always be approached with caution and sensitivity, as it can be triggering or offensive to some people.
