1) A mixture of the words, yetti, and idiot. Commonly used by snowboarders that like to party and drink alot of beer. A yettiot is much like a yetti, but in heat acting on a rampage. Yettiots can be found from the beaches of San Diego, to the snowy mountains of Big bear Lake. If you are ever to encounter a yetti while in his "yettiot" stage, you should run as fast as you can, or if its winter get on water. "Yettis cant swim in winter" And yettiots are always horny.
