First coined by Sarah Faye Pierce (from Association of Home Appliance Manufacturers) in her book 'My Lobbyist Agenda', magtrometer is a component used in futuristic microwaves to produce OEM microwaves. Since it is hazardous, trying to replace a magtrometer component may cause it to explode. The explosion may lead to fatal injuries to independent repair technicians.
Sarah: No, don't try to fix the magtrometer! It can explode.
Louis: Imma focken do it.
A magiros ma-gear-os is effectively a massive battler (i.e. one who tries and fails at most aspects of human activity). Although used as a common pay-out the word really means that you have reached the summit of human stupidity. Word origin comes from General P. Magiros who lead his troops to the highest recorded casualties in Australian-Colonial English battle records as he was ambushed while fixing his hair in his war tent.
