Magtrometer

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.
