Blood on the Dance Floor's song "S my D" from the album "It's hard to be a Diamond in a Rhinestone World", stands for "Suck my Dick!"

(Which they cleverly disguise as "Solve my Dilemma" on some of their older youtube videos).

S my D is also a commonly used word for many highschool aged teens to tell a girl (or boy) to suck their dick in an undercover form.

Also used as a comeback.
