Here's "23 skidoo" being used very theatrically, in 1907. But is this phrase the product of a poverty-stricken mind? "The deadly thing about slang," as we learn in The Country Gentleman, "is this: A phrase, for instance, 'I should worry,' or a single word like 'skidoo,' is made to stand for a whole class of ideas, each idea finely discriminated from every other idea in the same general class. But 'skidoo' does universal service in its class where a clear thinker would use, according to the shade of meaning, retreat, retire, depart, decamp, disappear, vanish, scamper, leave, escape, flee, or a long list of phrases. The poverty-stricken mind in a blurred sort of way falls back on 'skidoo,' and when that word is worn to the very bone someone invents a new word or phrase like 'beat it,' and then the changes are rung on that ad nauseam. Slang paralyzes fine thought disciminations, and, of course, a person who is doing no sharp, clear thinking is not looking for standard words to express exact shades of meaning. Poverty-stricken in ideas, the slang user is soon bankrupt in the gift of expression" ("Slang—and Its Remedy," 1916).
