When "frog-march" (also sometimes called "the frog's march") first appeared as slang around 1871, it meant to carry a prisoner (or a drunk being ejected from a bar) face down, with each of four husky men holding an arm or leg. The term comes from the resemblance the recipient of the procedure bears to a frog with its limbs splayed out. Today, however, "frog march" is usually used to mean the less dramatic (but equally effective) method of forcibly propelling a prisoner forward while pinning his arms behind him.
