It is a spoof on administration. Its official definition: Administratium is the heaviest element known to science and was recently discovered at a major US research university. The element has no protons or electrons and thus, has the atomic number 0. However, it does have one neutron, 125 assistant neutrons, 75 vice-neutrons and 111 assistant vice-neutrons, which gives it an atomic mass of 312. These 312 particles are held together by a force that involves the continuous exchange of meson-like particles called morons. Since it has no electrons, administratium is inert. However, it can be detected chemically as it impedes every reaction it comes in contact with.
