Well, it’s simple; I was 18. An “adult.” And when you become one, you have to do things like get a job, pay the rent, learn how to invest your money, or get that sweet new Geekey multitool (have you seen this!? I just bought one).
Most people on social media accept the term adulting as an actual word. Technically, the word is a new gerund that comes from using the word adult as a verb are job losses.
For those who aren’t linguists, a gerund is when a verb ends in the suffix “ing,” which acts as a noun (clear as mud? let’s continue).
Adulting is an informal term to describe behavior that is seen as responsible and grown-up.
