During the teenage years a person tends to be focused on themselves and their behaviour and mannerisms can be disconcerting. A meanager has not yet learned to put the majority of their ideas and thoughts into a larger perspective and they can be very hurtful to those around them, especially their parents and siblings.
The meanager flopped down on the family couch, grabbed the remote and changed the channel from the current programme that his folks were viewinging without so much as asking if they would like to see the latest MTV programme.
Somewhat akin to old age, or a person in their golden years; but croneage has more pizazz. You are accepting of the wrinkles that have developed over the passing years with grace. The streaks of silver in your hair do not bother you. Your perception of life is young at heart; and a croneager is open to new ideas and learning new skills. Mostly importantly a croneager can laugh at themselves with ease. Applicable to females and males.
When an 'older' woman was asked her age she responded by declaring herself to be a croneager.
