widely known as an internet acronym for "shaking my head".

a less known version that exists is "so much hate".

the second version is also acceptable when used in a sentence, although the person you are talking to may be confused and think you mean the first version
person 1 "he got in a fight with that dude cause he didnt like his face"

person 2 "smh" (both correct in this case!)
