👉 The word 'hidden necked' is not a commonly used term, as it can refer to something that isn't visible from above. However, when referring to someone who's secretive and keeps their secrets hidden, the phrase might suggest they're not open about things.
Here’s an edgy example: "Despite her reputation for being an overachiever, she often acts like a cat in a box, never letting on that she's actually a cat with two tails." This statement implies that she hides behind a mask of success to avoid revealing how hard work and dedication really paid off.
