the psycho-emotional drive to possess and acquire larger quantities of holiday decorations than reasonable persons would find excessive - for example, enough ornaments to overfill several more Christmas trees than safely fit into one’s home; ornadementia can in severe cases grow into an obsession for constantly buying ever more home décor of any category.
OMG, I don’t care that it’s 60% off! We don’t need another plastic statuette of Marilyn Monroe on any of our four Christmas trees! It’s just your ornadementia telling you that we need it, grrrl - just take a deep breath and hand me your wallet for safekeeping. Do it now.
