O.E. hoppian "to spring, dance," from P.Gmc. *khupnojanan (cf. O.N. hoppa, Du. huppen, Ger. hüpfen "to hop"). Slang noun sense of "informal dancing party" is from 1731 (defined by Johnson as "a place where meaner people dance").

"opium," 1887, from Cantonese nga-pin (pronounced HAH-peen) "opium," a Chinese folk etymology of the Eng. word opium, lit. "crow peelings." Re-folk-etymologized back into Eng. by association with hop (n.1).
