Smiffed

Being ignored on a social media platform. Usually by a friend who follows you closely, but envies your sweet photo/updates of your vacation in the Grand Canyon and therefore, refuses to give you the satisfaction of a "like", "favorite" or "retweet."

"How was your vacation?"
"It was great! I went hiking in the Grand Canyon!"
"Oh I saw your Instagram, way cool."
"You saw it? But you didn't like it..?"
"Oh... Yeah..."
"You smiffed me, man! You douche bag!"

Smiffed

The act of smacking someone hard across the face. Like Will did to Chris.

Man, that guy just walked up to him and smiffed him like a bad child. Yo keep it up and I'm gonna smiff yo ass. That chick was smiffing the hell out her old man.
