This works best with medium/long hair, but if it's too long, you may have a hard time tucking in the ends.

First, gather your hair into a low ponytail.

Start to twist it. it doesn't matter which direction you do it, just do whatever seems natural.

Start to pull your hair upward as you twist it.`

Twist it all the way up.

Here's the confusing part:

You have to turn the strand of your hair back on itself and sort of around so it makes a little bun on the top and...

...looks like a loop.

Tuck in the ends that stick out of one side (the left side here).

Fasten it in place with pencils, pins, chopsticks- whatever you have on hand.

Viola!
