shimmy

While it may sound a bit like "shimmer" or "shiver," *shimmy is about a quick, shaking, side-to-side movement. It is best known as a dance move, where a person rapidly shakes the shoulders or body in a lively way. Beyond dancing, the word also describes an unsteady vibration. A car's steering wheel might shimmy if the tires are off balance, or a washing machine might shimmy across the floor. It can also mean moving by twisting and wiggling, like when someone shimmies into tight jeans or shimmies* up a pole.

The word "shimmy" brings to mind lively movement and a bit of playful energy. It first became widely known as the name of a dance in the early 1900s, especially one marked by rapid shaking of the shoulders and upper body. Even today, that dance sense still feels vivid: it suggests motion that is fast, loose, and a little flashy.

But the word does more than describe dancing. In everyday English, it can refer to any quick wobbling or shaking motion. In a mechanical sense, a shimmy is an unwanted vibration, such as when a car, bicycle, or airplane starts to shake uncomfortably. You can also use it for the way a person moves by twisting and wriggling. Someone might shimmy into a tight skirt, shimmy through a narrow opening, or shimmy up a pole or tree by hugging it and inching upward.

Whether it is a dancer on stage, a rattling machine, or a person squeezing through a tight space, "shimmy" captures motion that is quick, shaky, and full of life. It sits somewhere between a shake, a wobble, and a wriggle, which is why it works so well in all of these scenes.
