Snarky?

In the last year I've heard the term "snarky" used four times.  (Okay.  So I don't get out much.)

I think I know what it means, from the way it was used.

I could look it up in some modern dictionary.  (It would have to be modern.  I'm fairly well-read and this word "snarky" has only recently crossed my radar.)  Makes me wonder if it has been infused into our culture by some line in a movie or tv show.  (You know, kinda like  "You go, girl!"  From whence came that?  And "snarky"?)

Yes, I could look it up, but I thought I'd have some fun.  How's about youse guys tellin' me your definitions?  Then I'll tell you if they line up with what I thought it meant.

Deal?  Deal.

Yours for expansion of vocabulary,
Hester
