- frog-march (n.)
[frog-march 词源字典]
- also frog's march, 1871, a term that originated among London police and referred to their method of moving "a drunken or refractory prisoner" by carrying him face-down between four people, each holding a limb; the connection with frog (n.1) perhaps being the notion of going along belly-down. By the 1930s, the verb was used in reference to the much more efficient (but less frog-like) method of getting someone in an arm-behind-the-back hold and hustling him or her along. As a verb by 1884.[frog-march etymology, frog-march origin, 英语词源]
