smuh

shake my unicorn head.
same meaning as "smh" but the added word "unicorn" puts the speaker higher above the other. Therefore, making themselves more dominant. Basically a classy way to judge someone using an abbreviation that they won't understand.
Dumb friend: "I just bought Justin Bieber's new cd!"

Cooler 'unicorn' friend: "... smuh."
Get the smuh mug.
