Portable Envy
Portable envy is envy (nonfiction) which is transportable separately from a person, for later experience.
Drug mules (nonfiction)
Early versions of portable envy were developed by clandestine drug manufacturers for use with Drug mules (nonfiction).
Drug mules
A drug mule is any animal (nonfiction) or artificial intelligence (nonfiction) which is a mule (nonfiction) due to the effect of drugs.
Drug mules spontaneous emerge from drug mules (nonfiction) when a container of portable envy activates prematurely.
This effect is exacerbated by the consumption, or even the nearby presence, of Extract of Radium.
Circuit boards
Later versions of portable envy exploited vulnerable components on circuit boards.
Manufacturers initially substituted cheaper components to save money during the Capacitor plague (nonfiction) years. Subsequently, pirate manufacturers have released knock-off circuit boards with built-in portable envy features.
