"SMD" is the perverted equivalent of "Smh." It is the acronym for "shaking my dick." Can be used when in disappointment of someone, preferably out of fun. It can also be used in the context for pure recreational sport, SMD'ing is a game to enjoy with friends. (Not literally, of course...unless you're into that.) Can also be written as "Smd," "S.M.D," or "smd."
"Aww man, I'm gonna bomb this test today..."
"You always were a failure...smd."

(just for random fun)
