A neologism that may work here is goblin mode:
Their goblin mode attitude defies societal expectations.
It was last year's Oxford Languages Word of the Year:
‘Goblin mode’ – a slang term, often used in the expressions ‘in goblin mode’ or ‘to go goblin mode’ – is ‘a type of behaviour which is unapologetically self-indulgent, lazy, slovenly, or greedy, typically in a way that rejects social norms or expectations.’
The key to this word is that it describes not just indulging in pleasures but doing so in a way that rejects conventional expectations. To someone who expects people to work, someone unapologetically not working would be pursuing a kind of goblin mode.
Many articles around the same time glossed goblin mode through the pursuit of pleasures that may set aside norms around responsible time-keeping, hygiene, or cleanliness:
It's mindlessly binge-watching television without worrying about the time. It's eating snacks in bed without a care about leftover crumbs. And it's wearing the same pair of pajamas all week while working from home. Welcome to "goblin mode." (NPR)
While it is a casual term often seen on social media, it has made its way into major news publications too, like when The Times of London published an opinion piece in which the author said too many people had embraced goblin mode "in response to a difficult year." (CBS News)
Many people adopted goblin mode, giving in to lazy behaviour, during the pandemic. (BBC News)
As seen in the last two examples, the word can be glossed as an embrace of a negative (e.g., lazy) behavior. It can also defend those relaxed norms, if an author is confessing their own goblin mode:
I might define goblin mode as “unbridled domestic liberation” or “a complete shedding of the mask of public life” or, my personal favorite, “staying home and getting weird.” Whatever you call it, I’m grateful for my newfound ability to go goblin mode. Now get out of my house so I can act unhinged. (The Atlantic)
