People also stretch slingshot as a verb「slingshot」也被拉來當動詞用: a car can slingshot past another car一輛車可以「甩過」另一輛車, and a spacecraft can slingshot around a planet太空船也可以「甩過」一個行星 — meaning it is thrown forward fast意思是被快速往前拋出, as if from that rubber band就像從那條橡皮筋射出一樣. The object這個實體物品（彈弓本身） is the home meaning才是它最主要的意思。
