腰 waist

When you YODEL, make sure and use your diaphragm muscle (located in your waist) to project your voice all the way to the next Alp.

To models, a slim waist is an important organ.

coward ★☆☆☆☆
腰 (waist) + 抜 (extract) = 腰抜け (coward)

coward - the nuance is someone who becomes paralyzed when the shit goes down. Someone who is too frightened to react.
