"Oh, it was a soaker [a sickening experience], Cig," he said. "Mike, my pal, he beefed [turned state's evidence], 'n' the screws [prison officers] they did me dirt from the start. Got the cooler [dark cell] ev'ry time I did en'thin'. Had fifteen days there twice. It was that killed me. But wait till I catch that gun Mike. It'll be his last beef if I ever find him." "Gun" means practically what "bloke," "stiff," and "plug" do--a fellow; but there is a shade of difference. It comes from the verb "to gun," to do "crooked work." Consequently a "gun" is more of a professional thief than is the "bloke." "Mug," on the contrary, is the exact equivalent of "bloke," but the verb "to mug" implies photography. In some cities suspicious characters are arrested on general principles and immediately photographed by the police authorities. Such towns are called "muggin' joints," and the police authorities "muggin' fiends." Some tramp words are popular for only a few years, and are then supplanted by others which seem to make the thing in question more vivid and "feelable." Not so very long ago, "timber" was the favorite word to describe the clubbing given to tramps in certain "horstile" towns. A hobo has recently written me that this word is gradually giving way to "saps," because the sticks or clubs used in the fracas come from saplings cut down for the purpose. On account of this continual change it is difficult to keep up with the growth of the language, and in my case it has been particularly so because I am not regularly in the life. If one, however, is always in the way of hearing the latest expressions, and can remember them, there is not much else in the language that is hard. The main rule of the grammar is that the sentence must be as short as possible, and the verb omitted whenever convenient. As a general thing the hoboes say in two words as much as ordinary people do in four, and prefer, not only for purposes of secrecy, but also for general intercourse, if in a hurry, to use their own lingo.
