Why is "Grunge lit" trending?

Wikipedia Overview

Grunge lit is an Australian literary genre usually applied to fictional or semi-autobiographical writing concerned with dissatisfied and disenfranchised young people living in suburban or inner-city surroundings, or in "in-between" spaces that fall into neither category. It was typically written by "new, young authors" who examined "gritty, dirty, real existences", of lower-income young people, whose egocentric or narcissistic lives revolve around a nihilistic or "slacker" pursuit of casual sex, recreational drug use and alcohol, which are used to escape boredom. The marginalized characters are able to stay in these "in-between" settings and deal with their "abject bodies". Grunge lit has been described as both a sub-set of dirty realism and an offshoot of Generation X literature. The term "grunge" is a reference to the US rock music genre of grunge.
