Take the word "bughouse," for example. As it is now used it means actually crazy, and when first used it signified a state of mind bordering on insanity; but it was not invented for purposes of secrecy. Old Boston Mary was the originator of it. Sitting in her little shanty one day, and talking with some tramps seated about her, she exclaimed suddenly: "Blokes, I'm bughouse." Asked what she meant, she said: "I'm losin' me brain." It hit off exactly her poor, failing condition, and the word went like a flash all over America. To-day it is the most popular word in the lingo for the ordinary word "insane." "Crippled under the hat" is also heard, but "bughouse" supplants this expression on all occasions when men talk to their fellows, and not to the public. It is most interesting to ferret out the origin of these words. Many of them are so old that no one remembers exactly how they came into popularity, and even about words more or less modern there are different explanations; but I have succeeded in a number of cases in getting fairly trustworthy stories. In Chicago I met, one day, the man who, according to report, was the first to use the tramp word for a Catholic priest, "Galway." He was nearly eighty years old when I saw him, but remembered very distinctly how he came by it. "I was batterin'," he said, "one moon [night] on the Dope [Baltimore and Ohio Railroad], an' a stiff 'e says: 'Blokey, squeal at that house over there--it's a priest; he'll scoff ye.' I goes over 'n' toots the ringer [bell]. The baldy [old man] 'e comes himself, 'n' asted what I wanted. 'I'm starvin', father,' I yapped, 'n' begun to flicker. 'Go 'way, you lazy man,' 'e said; 'I've fed ten like you since noon.' I was horstile. I dunno how the word come to me, but I yapped it in his phiz: 'Y' ole Galway, you, yer an ole hypocrite'; 'n' then I mooched. Lots o' words comes to me that way when I'm horstile." "Punk" is another interesting word. Some say that it comes from the French word _pain_, and immigrated to the United States from Canada, where the hoboes had heard their Canadian _confrères_ use it; and this may be the case. Certainly it is as near the French pronunciation as the average vagabond can come. But a more natural explanation is that punk being dry, and bread, particularly that given to tramps, being also often dry, the resemblance of the two impressed itself on some sensitive tramp's mind. The disgust with which beggars frequently speak the word helps to substantiate this theory. "Flicker," meaning to faint, comes from the flickering of a light, "battering" (begging) from knocking at back doors, and "bull" (policeman) from the plunging, bullying attitude of these officers when dealing with rowdies.
