An action that serves no purpose other than showing someone you can do something, regardless of the financial, physical or emotional cost. The offenders name is usually Chris or Mandy.
Chris is such a point prover! He tailgated 5 feet off that truck’s bumper, traveling 80 mph, to show his anger for being cutoff!
You lift up your shirt, wear your pants backward, do a handstand, and take a big shit through your zipper hole. Then you ask your mother once she is finished with her dinner if she could kindly wash your nutsack.
Hey man, I just took the biggest shit of my life.
Did you make sure to lift up your shirt? Its a common courtesy thing.
No, I wasn't properly shitting.
