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!"

A snifferoo is a slient but super stinker fart that causes people to go "sniff, sniff", and then exclaim "OOOuuuueewwh!"
