Teri Landreth uses this word and I thought she made it up!

Snark, Snarkiness or Snarky - It's a real word.

A word that should be googled to find the definition as per direction from Dane Cook. It means short tempered or irritable. "He was being very snarky with me. Yeah, snarky. Its a word, google it." -Dane Cook
We also added de-snark. When one is snarky with you and they apologize, you can call that a de-snark. Wow, the first known use of the word was in 1906. Never heard of it until I heard Teri use it. Don't be snarky, always un-snark.
