Formation

Slang expressions are created by the same processes that affect ordinary speech. Expressions may take form as metaphors, similes, and other figures of speech (dead as a doornail). Words may acquire new meanings (cool, cat). A narrow meaning may become generalized (fink, originally a strikebreaker, later a betrayer or disappointer) or vice-versa (heap, a run-down car). Words may be clipped, or abbreviated (mike, microphone), and acronyms may gain currency (VIP, AWOL, snafu). A foreign suffix may be added (the Yiddish and Russian -nik in beatnik) and foreign words adopted (baloney, from Bologna). A change in meaning may make a vulgar word acceptable (jazz) or an acceptable word vulgar (raspberry, a sound imitating flatus; from raspberry tart in the rhyming slang of Australia and Cockney London; (see Jargon). Sometimes words are newly coined (oomph, sex appeal, and later, energy or impact).
