full nester noun [C]
UK /ˈfʊl ˌnes.təʳ/ US /ˈfʊl ˌnes.tɚ/
someone whose adult children are still living at home
To cope with the additional cost of having their adult children living at home for longer, the report finds that full nesters are making greater financial sacrifices than empty nesters across the board, with some putting their own financial future at risk … A third of full nesters report that they are contributing less to their savings, while more than one in four are spending their savings to meet the cost of everyday living.

trad son noun [C]
/ˈtræd ˌsʌn/
an adult male who lives at home with his parents and does tasks such as housework and gardening in return for free accommodation
A “trad son” is a term that has emerged from social media to describe a young man — usually in his 20s or 30s — who lives at home with his parents, often without working full-time or contributing financially, while embracing a domestic lifestyle. Unlike traditional expectations of adulthood, trad sons prioritize comfort, convenience and household responsibilities.

grad annexe noun [C]
UK /ˈgræd ˌæn.ɪks/ US /ˈgræd ˌæn.ɪks/
a self‑contained living space for a young adult, located on the same property as their parents’ home, which provides free or low‑cost accommodation
Chloe Combi, author of the book Generation Z: Their Voices, Their Lives, says she has seen a huge spike in garden cabins and annexes, including “parents building granny flats that no longer house grannies but their twentysomething and soon thirtysomething kids”. These so-called grad annexes are a notable trend as “the cost of living crisis deepens and house rental and ownership becomes less viable for Gen Z”.
