The disorder in which
the volume of the
television or computer must be a multiple of 5, (or sometimes just even or just odd numbers). If it is not on the preferred volume the person may get stressed, or agitated and will go out of their way to get the volume on their preferred number. They will do this in every
environment, whether its in a public place or at someone else's house. People like to joke about it by putting the volume on '31' not '30' and then leaving the room... to these people I would like to say... I hate you.
