lug (n.): 1620s, "handle of a pitcher," from lugge (Scottish) "earflap of a cap, ear" (late 15c.; according to OED, the common word for "ear" in 19c. Scotland), probably from Scandinavian (compare Swedish lugg "forelock," Norwegian lugg "tuft of hair"). The connecting notion is "something that can be gripped and pulled." Applied 19c. to mechanical objects that can be grabbed or gripped. Meaning "stupid fellow" is from 1924; that of "lout, sponger" is 1931, American English. Compare lug-nut (1869), nut closed at one end as a cap.

lulu (n.): "remarkable person or thing," 1886 (first attested in a baseball article from New Orleans, U.S.), of uncertain origin; some suggest a connection to earlier looly "beautiful girl," of unknown origin. But the reference more likely is to Lulu Hurst (1869-1950), the "Georgia Wonder," who was a popular attraction 1883-85 demonstrating her supposed mysterious "force" that allowed her to effortlessly move, with just a light touch, umbrellas and canes held tight by others. She barnstormed the U.S. and, at 15, was, briefly, one of the most famous women in the land. The skeptics soon explained her trick and burst the bubble, but not before her name was used as a word:
Such [musically uneducated persons] start from the avowed or unavowed supposition that the pianist or violinist's art necessitates no higher qualities than does plate-spinning, dancing, or the feats of a Lulu. ["The Hero as Virtuoso," in "London Society magazine," 1883]
