ChristoSadist
ChristoSadist are All those people who deliberately and intentionally inflict/impose Christmas upon the rest of us for their own joy, satisfaction, and pleasure.
When a family member is a ChristoSadist they organise the entire Christmas holiday 'event' to their own personal agenda for their own satisifaction, and expect everyone to do as planned and prepared - no matter how inconvenient or unwanted the actually just being there is to everyone else. The ChristoSadist takes great joy in forcing everyone to march to the beat of their drum and anyone who does not follow the rules that are clearly laid out, will be forever accused of ruining the day!
