post-Idealism 

In essence, an ideal compromise. Though retaining idealism, it is put into a democratic context, where opposing views have opposing ideals.

Person A: I want to go shopping first.
Person B: I want to eat first.
Person A: Let's go to David Jones. I can shop, and you can sit in the food hall, and help me choose what to buy while you eat.
Person B: post-Idealism!

Post-Adolescent Idealistic Phase 

A person who just graduated high school/college student who tries to act like an adult, but still behaves like a high-schooler. They usually tend to use large words, pretending to have a large vocabulary because they think that it makes them look smart and impressive. Tend to think they know everything. (hint-the whole cast of "Real World")

"What, is Josh still trippin because he is in his Post-Adolescent-Idealistic Phase?"

Post-Adolescent Idealistic Phase 

The time after the pointless teen years in which a young person develops what are called "standards" and "morals." It is a time in which eyes are opened and "The Truth" suddenly becomes clear.

Usually beginning when one enters college, said young person reads deep literature, searches for the meaning of life, and listens to college radio, all the while secretly becoming even more confused than when he/she was an lame 16 year old.

The Post-Adolescent Idealistic Phase usually entails naive 18-20something year olds upholding hopeful, yet unrealistic morals. Often, utopian dreams can be confused for "The Truth."

After the phase has ended, the young person must beware becoming highly hypocritical and/or jaded once life has slapped them around a bit.

"Is Josh giving you shit because he going through his post-adolescent idealistic phase?"

Post-Interaction Idealistic Rumination

The process of ruminating on what one should have done or said in an interaction that just transpired or transpired earlier. During PIIR the individual typically undergoes feelings of self-abuse, anger, and/or embarrassment.

"Dude, I could have earned way more brownie points with Paige had I just tried to be more flirty. Now she probably thinks I'm a wank or thinks I’m not interested in her. Wait. Shit, SHIT! I gotta snap out of this PIIR."
"You're not a wank. And what's PIIR?"
"Post-Interaction Idealistic Rumination."
"That's quite a mouthful."
"Indeed."

or:

"I just agreed to go to church every Sunday morning with my neighbor. What the shit was I thinking?! I should have told him I'm busy literally every Sunday morning! #Fuckmylife."
