A mythical substance which is supposededly vital to the functioning of electronic equipment. Therefore when the magic smoke leaks out, the equipment stops working.

This term is often heard when some hapless individual wires equipment up backwards or to the wrong voltage supply, causing the circuit boards to fry. At this point, some wag will say "that won't work again, because you've let the magic smoke out".

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

The essential essence that lives inside of all electronic parts. If the smoke is allowed to leave the device, it will no longer work. The smoke can never be put back again.
