Dex, The Cookie Monster

Guess what?  I have a new favorite word.  Know what it is?  Of course not, only I could know that.  Okay, okay, I'll throw you a few hints: it refers to something flat and round (similar to the Earth (what does that Columbus dude know?!)), is full of chips (of the chocolate persuasion, not my typical Vegas casino chips), tastes delicious and rhymes with "Snooki" (although what I'm referring to is far more attractive, less plump and not quite as tan).  Give up?  Check out the video below for the answer.
