What does “chill-ness” mean?

To paraphrase Jeff Foxworthy, You might be a chiller if…

  • you’ve got nothing to prove
  • you’re comfortable with yourself and effect comfort in those around you
  • you don’t domineer but won’t be intimidated
  • you’re relaxed and in control
  • you don’t think everyone else ought to be just like you
  • you take it all in and enjoy the ride
