reality segmentation violation - noun phrase - A syndrome in which someone is so deep inside their own little world that any utterly mundane activity can provoke a combination of emotional upset, anger, confusion because they simply never think about it. In children this phenomenon also typically includes running to authority figures to inform on someone in the most agitated way possible. This is bewildering to just about anyone nearby who is not focused solely on their own little worlds.
A sample stack trace of a reality segmentation violation:
A: "Hey - you pooped in the bathroom!"
B: "Yes.... and?"
A: "But but but - you pooped! In! The bathroom!"
B: "Isn't that one of the things you're supposed to do?"
A: "You pooped in the bathroom!"
B: . o O ( What the Kentucky Fried Fuck? )
B: "Yes. I pooped. In. The bathroom. That's where you're supposed to go to the bathroom."
This exchange will typically go on for as long as all entities involved are still within visual range.
