SMH, an acronym for 'shaking my head,' emerged in the early 2000s as a staple of internet slang and text-based communication. It is used to convey a wide range of emotions, from mild annoyance and disbelief to profound disappointment in someone's actions or a specific situation. As meme culture evolved, SMH transitioned from a simple text response to a genre of reaction images and GIFs featuring celebrities, characters, or animals looking visibly frustrated. Whether it's a person facepalming or a slow head-shake, the SMH meme remains one of the most relatable ways to signal that words simply aren't enough to describe how ridiculous something is.
