One of the most popular sleeping positions when traveling. The head is tilted to a side resting on a window, seat belt, pillow, etc. Resembles a position you would make with your head when eating a taco. Results in neck pain and a really shitty nap.
That overnight bus to Phoenix killed me. I had taco neck the whole time.
