This is an excerpt from Jonathan Kay's review of "18 Months" by Shannon Thrace. I'm posting it here because I think it describes this pattern well.
"Nor does Shannon find allies among the friends who populate Jamie’s social orbit and enable his narcissism. For the most part, these are childless, underemployed, superannuated adolescents who spend a lot of time in imaginary realms created through video games, Dungeons & Dragons, science fiction, and live storytelling shows. When it comes to the younger set, Shannon describes “a penchant for undercuts, often dyed blue, [with] names that evoke Victorian toddlers: Larkin, Duncan. Two Quinns. Two Flynns.” At an older trans couple’s home, she observes:
tall stacks of comic books teeter[ing] alongside fantasy novels and the complete Twilight series on DVD. The bookshelves are dotted with superhero figurines, a bendable Grey alien and a Starship Enterprise model. Under the large-screen TV, a PlayStation sits wedged between an old-school Atari, a Dr. Who Lego game and a Magic: The Gathering card deck.
