Habitarian
A habitarian is someone who doesn't know the meaning of the word 'change.' They're like a zombie. They just keep doing the same thing, even if it's nonsense.
We've always had the same stupid welcome message. Why change it? 'That's how it's always been.'
We've always used the same broken printer. Why fix it? 'That's how it's always been.'
We've always used the same password. Why make a new one? 'That's how it's always been.'
