Like a 3 year old.
Not being okay with some spoiled rotten mollycoddle trying to walk over somebody isn't a childish thing to get angry about, it's a legitimate thing to get angry about and stay angry about, especially when the one that got angry knows the mollycoddle takes nothing seriously and holds nothing sacred, and lies about everything and has told the one they got angry they needed to wake up and fight.

Immature and irresponsible actions between a pair of "less than grown up" lovebirds which results in da girl's soon having to start "eating for two".

Holding in all of the aggravating, stupid, child-like statements inside of your head until you feel it is the right time to let them out.
Mature person: “So what made you decide to act in such a childish way today?”
Childish person: “ I have held it in and waited, but now that I know you feel better I am returning to my childish ways”
Mature person: “Oh, well I am not surprised”

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.
