"prissy person, prim girl, effeminate man," 1914, Southern U.S. colloquial, a back-formation from prissy (q.v.).
"sexual attractiveness," 1937 (umph), suggestive visceral physical sound. Ann Sheridan (1915–1967) was the original Hollywood oomph girl (1939).
1540s, mynx "pet dog," later (1590s) "a young, pert, wanton girl" [Johnson], also "a lewd woman," a word of uncertain origin, perhaps a shortening of minikin "girl, woman," from Middle Dutch minnekijn "darling, beloved," from minne "love" (see minnesinger) + diminutive suffix -kijn (see -kin). Klein's sources suggest the word is from Low German minsk "a man," also "an impudent woman," related to German Mensch (see mensch), which in vulgar use also has a sense of "wench, hussy, slut."
"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."
