The reasons given are, in order of frequency, that slang was more emphatic, more exact, more concise, convenient, sounded pretty, relieved formality, was natural, manly, appropriate, etc. Only a very few thought it was vulgar, limited the vocabulary, led to or was a substitute for swearing, destroyed exactness, etc. This writer attempts a provisional classification of slang expressions under the suggestive heads of rebukes to pride, boasting and loquacity, hypocrisy, quaint and emphatic negatives, exaggerations, exclamations, mild oaths, attending to one's own business and not meddling or interfering, names for money, absurdity, neurotic effects of surprise or shock, honesty and lying, getting confused, fine appearance and dress, words for intoxication which Partridge has collected,[10]for anger collated by Chamberlain,[11] crudeness or innocent naïveté, love and sentimentality, etc. Slang is also rich in describing conflicts of all kinds, praising courage, censuring inquisitiveness, and as a school of moral discipline, but he finds, however, a very large number unclassified; and while he maintains throughout a distinction between that used by boys and by girls, sex differences are not very marked. The great majority of terms are mentioned but once, and a few under nearly all of the above heads have great numerical precedence. A somewhat striking fact is the manifold variations of a pet typical form. Twenty-three shock expletives, e.g., are, "Wouldn't that ---- you?" the blank being filled by jar, choke, cook, rattle, scorch, get, start, etc., or instead of _you_ adjectives are devised. Feeling is so intense and massive, and psychic processes are so rapid, forcible, and undeveloped that the pithiness of some of those expressions makes them brilliant and creative works of genius, and after securing an apprenticeship are sure of adoption. Their very lawlessness helps to keep speech from rigidity and desiccation, and they hit off nearly every essential phrase of adolescent life and experience.
