absquatulate v.

mid-14c., "to crush;" early 15c., "crouch on the heels," from Old French esquatir, escatir "compress, press down, lay flat, crush," from es- "out" (see ex-) + Old French quatir "press down, flatten," from Vulgar Latin *coactire "press together, force," from Latin coactus, past participle of cogere "to compel, curdle, collect" (see cogent). Meaning "to settle on land without any title or right" is from 1800. Related: Squatted; squatting.

"run away, betake oneself hastily to flight," American Civil War military slang noted and popularized in newspapers from the summer of 1861, originally often skadaddle, a word of unknown origin. There is an earlier use in a piece reprinted in Northern newspapers in 1859, representing Hoosier speech. Perhaps it is connected to earlier use in northern England dialect with a meaning "to spill, scatter." Liberman says it "has no connection with any word of Greek, Irish, or Swedish, and it is not a blend" [contra De Vere]. He calls it instead an "enlargement of dial. scaddle 'scare, frighten.'" Related: Skedaddled; skedaddling. As a noun from 1862, "a hasty flight."

For the benefit of future etymologists who may have a dictionary to make out when the English language shall have adopted "skadaddle" into familiar use by the side of "employee" and "telegram," we here define the new term. It is at least an error of judgment, if not an intentional unkindness, to foist "skadaddle" on our Teutonic soldiers. The word is used throughout the whole Army of the Potomac, and means "to cut stick, "vamose the ranche," "slope," "cut your lucky," or "clear out." [New York Post, October 1861]

"to upset, embarrass," 1834, discombobricate, American English, fanciful mock-Latin coinage of a type popular then. Compare, on a similar pattern, confusticate (1852), absquatulate (1840), spifflicate "confound, beat" (1850), scrumplicate "eat" (1890). Related: discombobulating; discombobulation.
