hip line
n.— «The side panel lines just beneath the windows—”hip lines” in auto industry parlance—slant upward. Viewed from the front in conjunction with the triple-lipped face, the look is delightfully menacing, sort of like the Impreza WRX is smiling in preparation for consuming something lower in the food chain.» —“A Real Driver’s Car on an Everyman’s Budget” by Warren Brown Washington Post Jan. 29, 2009.
