What does SMDH mean?

SMDM means “shaking my damn head.” “SMDH” is a text abbreviation that someone writes when they are very frustrated or strongly disapprove of something (e.g., “My connecting flight just got delayed for 5 hours, so I’m stuck at the airport. SMDH”).

Because “SMDH” technically has an expletive (curse word), it’s probably not a good slang abbreviation for the workplace.

When you’re writing about things that frustrate you, why not try the QuillBot Paraphraser. It can show you different ways to say the same thing so that you don’t offend anyone.
