Describes a boy's body as thin as a toothpick.

Toothpicks are usually small thin sticks that are pointed at one end or both ends. They also have a hook-shaped front end. The flat end of a toothpick with a pointed end can be broken off to hold the toothpick head.

Toothpicks should be hard, smooth and burr-free. The top should be slightly thin but not too sharp. It should not change color or taste after being soaked in water and the tip should not become soft. Some inferior brands on the market are inferior. Bleaching toothpicks with industrial hydrogen peroxide will cause great harm to the human body. It is recommended to use high-quality products from regular manufacturers and try not to choose products with unnatural white toothpicks.
