Sleazy [BEST]
1640s, of textile fabric, "downy, fuzzy," later "flimsy, unsubstantial" (1660s), a word of unknown origin. One theory is that it is a corruption of Silesia, the German region, where thin linen or cotton fabric was made for export. Silesia, in reference to cloth, is attested in English from 1670s; and sleasie, sleazy as an abbreviated form is attested from late 17c., but OED finds the evidence to be against "any original connexion." The sense of "sordid, squalid" is from 1941. Related: Sleazily; sleaziness.
Sleazy
Still, the tune itself is irresistible. DeMarco already has a knack for crafting warm, infectious guitar hooks, and "Baby's Wearin' Blue Jeans" filters that lo-fi pop aesthetic through an eerie wash of glam. The backing track has all the carefree breeziness of a Puro Instinct or Real Estate tune, but DeMarco's cruise-control vocals channel Marc Bolan "Jeepster" vibes. It's those slowed-down vocal manipulations that beget all the ambiguity of intention; they lend a sense of "story" to a song that would have been lost had DeMarco stuck to a higher register. Suddenly, its otherwise innocent groove becomes alluringly sleazy. That is to say, by the time DeMarco sings, "Stick with me forever / Don't take off those jeans," it's hard not to humor him. 041b061a72
