Smd is the acronym for "shake my dick." This term is used in response to people on the internet when they say attempt to sound profound when disagreeing with you but have have nothing to say besides"smh" which is the acronym for "shake my head." This term was coined after being fed up with prepubescent kids online thinking they're the shit.
Little kid - "smh I'm too cool for that"

Robert - "smd you're not fucking cool. Go to school and learn something. THAT'S fucking cool."
