dog robber

Origin: There are many conjectures about the origin of this term, ranging from the peacetime occupation of the title character in The Good Soldier Švejk by Jaroslav Hašek, to the use of the term dog for enlisted men, hence someone who took the best of everything away from the dogs to give to the officers. The most likely conjecture is that it comes from a 19th-century term for a contemptible person who stole scraps of leftover food that would otherwise be fed to dogs.
