a parent that desires to be more of a friend to their child versus a disciplinarian, mentor, teacher. They let their child run amuck in every neutral space without the child fearing any consequence for any bad behavior, no matter how disruptive that behavior is. The ultimate goal of the "said parent" is to raise a friend or a companion, not a self-sufficient and well-mannered member of society.
RobBot, Skywalker and I could have had a better time at the "Imagine Dragons" concert had it not been for the Frierant next to us who bought a very disruptive six-year-old to the show filled with drunk and "super high" adult concertgoers.
