Internet abbreviation. Used to refer to the act of shaking ones dickhead ("shaking my dickhead").
May also be used in a metaphoric way, e.g. you consider something as that nonsensical and unacceptable that "shaking my head" would seem understated or too posh.
literal example:
A: man, I have no toilet paper
B: just shake your dickhead

A: okay I am smdh

metaphoric example:
A: dude, my city council decided to build a sewage treatment plant in the middle of the old town
B: smdh
