I think this stands for "salted meat hug." Basically, it's when someone hugs you when holding a bunch of beef jerky.
"You got arrested again? How could you be so stupid? Smh." My girlfriend texted that to me. I think the salted meat hug was to console me.

An annoying and over-used initialism (not an acronym) meaning "shaking my head" or "shake my head".

It is used by idiots when they think they are "winning" an argument on the internet, but are actually just spouting incoherent nonsense and calling other people idiots without any evidence.

Yeah, you've met that guy, too, haven't you?

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!)
