" social contract "

 [ "Social Contract" ]

1: The unwritten, unspoken rules of polite society. It's what keeps you from laughing or commenting on bodily functions that happen in public and ignoring homeless/smelly people until you can escape their visual/audible range. May also apply to catching someone doing something inappropriate in public, in which both parties act like nothing happened and/or nothing was seen.

  * e.g.,  ... I went into the bathroom to wash my hands just as David was flushing the toilet. His shit stunk so bad, it was all I could think about. I tried to hold my breath and ignore it as the social contract keeps me from acknowledging the fact that his shit smell was suffocating me. 

 [ "Social Contract Disorder" ]

1: A person who is a lying manipulative, conniving individual who will use other people and has no compassion or decency for the people around them or for the social they belong to. It's antisocial personality disorder but with a more accurate name.

  * e.g.,  ... Person 1: Justin Manipulated me!
