Get the Childishmug. Some spoiled rotten dork claiming something that was never hers to take (because she thought it was owed her) or offer someone else isn't a childish thing for someone to get angry about, it's a legitimate reason for someone to be angry.

Get the childishmug. A stigma (rather than the akcual condition) associated with young adults aged 18 and over, particularly those who have graduated high school, who still remain living with their parents. This term implies a perception of immaturity or inability to take on adult responsibilities, often linked to financial constraints.
Society tends to view young adults who still live at home as childish, overlooking the financial realities that make moving out a challenge for many.
