Waist
You're flying a helicopter and you see a woman in the moon light touching her waist. She has both hands on her waist, like she's Wonder Woman or something. But it's the middle of the night. What is she doing?
Imagine flying your helicopter closer to the woman, it's not so hard because you have lots of moon light to see in, and try to see why she's touching her waist.

As you get closer you realize her waist looks weird and... puffy? You bring the helicopter down and see that the woman's waist looks incredibly cozy (こし)! She has a blanket balled up and tied around her waist, she's holding it there with her hand, probably because it's cold out at night. But even with just her waist covered, she looks so warm and cozy!
Imagine how cozy your waist would be if you tied a nice warm blanket around it.
