ACIS is more harmful to those coming in contact with the ACIS person than the ACIS person him/herself. Even casual contact results in looks of disbelief, screaming and the uncontrolable urge to place one's hands over one's ears and yell "Make it stop".

Not to be confused with having Head-Up-Assitisis or Asshatoses.
