the grown-ups are talking 

An overly derogatory and condescending way of telling someone that their input in a given conversation is childish and/or uneducated and will not heighten the level of intelligence in the discussion.

Also is used when one is short-tempered and unwilling to deal with more than one person in a heated discussion.

Person 1: What country do you think is the most technologically advanced in the world?

Person 2: Well Japan has to be in the top three - if not the number one most advanced in the world.

Person 3: Somalia's gotta be up there too.

Person 2: Okay, the grown-ups are talking. Just stand over there.

Buying a home is a sign that you have reached grownuppity.

Grown-Ups 

Hypocritical people. This is about the mindset specifically NOT your biological age.

Grown-Ups come in all shapes, sizes, and forms, but there is so many of them.

real grownup job 

A form of employment which pays well enough that the employee is mostly if not completely fiscally self-sufficient.

A real grownup job often but not necessarily requires postsecondary education and a 40+ hour work week. It may or may not involve working in an office, and may or may not be enjoyable or fulfilling. The primary qualification is that the job pays well enough for a responsible adult to live in a reasonably modest but comfortable manner with little or no outside help, be it in the form of a second job, trust fund or other form of mooching.

"Dude, I'm getting pretty fucking sick of being a broke ass college kid. I need a real grownup job."

Grown-Ups 

Referring to rims, blades, pancakes, wheels, whatever you fancy. To be considered grown-ups you must have wheels that are atleast 21" in diameter, hence the age limit for an adult. Although some consider 18" wheels grown-ups, many southern cultures would consider those to be teenagers.

Guy 2: What kind of sick, twisted world do we live in...?
