Origin and history of rapscallion

"coarse, frolicsome girl or woman," mid-15c., rampe, "a virago, shrew," perhaps from early senses of ramp (v.) via the notion of "rear up on the hind legs to attack," hence, of persons, "to attack like a rampant animal." Also compare ramp (n.1). Johnson's Dictionary (1755) has romp: "a rude, awkward, boisterous, untaught girl."

mid-14c., rascaile "people of the lowest class, the general mass; rabble or foot-soldiers of an army" (senses now obsolete), also singular, "low, tricky, dishonest person," from Old French rascaille "rabble, mob" (12c., Modern French racaille), as Cotgrave's French-English Dictionary (1611) defines it: "the rascality or base and rascall sort, the scumme, dregs, offals, outcasts, of any company."

This is of uncertain origin, perhaps a diminutive from Old French rascler, from Vulgar Latin *rasicare "to scrape" (see rash (n.)) on the notion of "the scrapings." "[U]sed in objurgation with much latitude, and often, like rogue, with slight meaning" [Century Dictionary]. Used also in Middle English of animals unfit to chase as game on account of some quality, especially a lean deer. Also formerly an adjective.
