tiger city
n.— «UWO Chancellor Richard Wells is well aware of Wisconsin’s up-and-coming cities. They are often referred to as “tiger cities”—mid-sized metros with suburban, if not rural, fringes. They have developable land, affordable housing stock and quality UW schools nestled within their bounds.» —“Editorial: Growth spurt at UWO beneficial to region” Oshkosh Northwestern (Wisconsin) June 6, 2007.
