What does "smh" mean?

“smh” is an acronym that stands for “shaking my head.” It is often used in texting, social media, or online conversations to express disappointment, frustration, or disbelief towards something that was said or done. For example, if someone makes a statement that is offensive or ignorant, another person might respond with “smh” to indicate that they are shaking their head in disapproval. The acronym has become increasingly popular in modern communication, particularly among younger generations who frequently use slang and shorthand in digital conversations.
