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.

When your eating a girl out, who has giant mud flaps, her beef curtains fall down around your neck. This forms a taco neck.
