--I think there is one habit,--I said to our company a day or two afterwards--worse than that of punning. It is the gradual substitution of cant or flash terms for words which truly characterize their objects. I have known several very genteel idiots whose whole vocabulary had deliquesced into some half dozen expressions. All things fell into one of two great categories, --FAST or SLOW. Man's chief end was to be a BRICK. When the great calamities of life overtook their friends, these last were spoken of as being a GOOD DEAL CUT UP. Nine-tenths of human existence were summed up in the single word, BORE. These expressions come to be the algebraic symbols of minds which have grown too weak or indolent to discriminate. They are the blank checks of intellectual bankruptcy;--you may fill them up with what idea you like; it makes no difference, for there are no funds in the treasury upon which they are drawn. Colleges and good-for-nothing smoking-clubs are the places where these conversational fungi spring up most luxuriantly. Don't think I undervalue the proper use and application of a cant word or phrase. It adds piquancy to conversation, as a mushroom does to a sauce. But it is no better than a toadstool, odious to the sense and poisonous to the intellect, when it spawns itself all over the talk of men and youths capable of talking, as it sometimes does. As we hear flash phraseology, it is commonly the dishwater from the washings of English dandyism, school-boy or full-grown, wrung out of a three-volume novel which had sopped it up, or decanted from the pictured urn of Mr. Verdant Green, and diluted to suit the provincial climate. --The young fellow called John spoke up sharply and said, it was "rum" to hear me "pitchin' into fellers" for "goin' it in the slang line," when I used all the flash words myself just when I pleased. --I replied with my usual forbearance.--Certainly, to give up the algebraic symbol, because A or B is often a cover for ideal nihility, would be unwise. I have heard a child laboring to express a certain condition, involving a hitherto undescribed sensation (as it supposed,) all of which could have been sufficiently explained by the participle--BORED. I have seen a country-clergyman, with a one-story intellect and a one-horse vocabulary, who has consumed his valuable time (and mine) freely, in developing an opinion of a brother-minister's discourse which would have been abundantly characterized by a peach-down-lipped sophomore in the one word--SLOW. Let us discriminate, and be shy of absolute proscription. I am omniverbivorous by nature and training. Passing by such words as are poisonous, I can swallow most others, and chew such as I cannot swallow.
