boom boom noun [U]
/ˈbuːm ˌbuːm/
a trend in fashion and culture that suggests wealth, glamour and confidence, often inspired by similar trends of the 1980s

Boom boom is glamour and greed, epitomised by a style and mindset reminiscent of the sleazy, money-saturated world of late 80s New York. There is an end-of-empire, end-of-history nihilism to it, a sense of raising another bottle of Moët into the air while the world burns around you. But it’s also about aspiration, panic and the jarring disconnection between the economic climate we want and the one that exists – an experience shared by most.
