adulting noun [U] UK ‘æd.ʌlt.ɪŋ US ə’d.ʌlt.ɪŋ
doing things that are associated with being an adult

A few nights ago, I got home from work and sat on my bed, scrolling through Twitter. I didn’t get far in my timeline before I saw a tweet from a twentysomething who said she was “adulting” because she cooked herself dinner. Ugh.

an arrangement where the children of a couple who have separated remain in the family home and their parents take it in turns to live with them there

sharenting noun [U] UK ‘ʃeə.rənt.ɪŋ US ‘ʃe.rənt.ɪŋ
using social media excessively to share information about one’s children

In the United States, according to a survey, 90 per cent of two-year-olds have a presence on social media … The UK is going the same way. There is a commensurate rise in concern that sharenting — obsessive peacocking about your offspring’s looks, sporting achievements and toilet-training schedule — could be damaging.
