shock wave
Typically, when air is displaced by a pressure wave, it moves at the speed of sound. These pressure waves can be generated from one's vocal cords (when speaking), the vibration of an object, or the impact of one object against another. However, in certain cases, the pressure wave is generated by a collision between air parcels, such as when lightning heats the air immediately around it. This rapidly-expanding air crashes into the cooler air around it, generating a massive spike in pressure followed by a sharp drop-off. It is this sharp spike and drop-off combination that differentiates a sound wave and a shock wave. Shock waves can be either naturally generated, in the case of volcanic eruptions, lightning strikes, and asteroid impacts; however, they can also be generated through man-made means, such as explosives that derive their power either from chemical energy that is converted into thermal energy or by way of nuclear fission or fusion. If the pressure differential occurs in air where clouds can condense, the act of high pressure passing through the area and low pressure following can cause temporary "Wilson clouds" to form.
The shock wave generated by the explosion in Beirut generated Wilson ring clouds and severely damaged the city of Lebanon.

pod person
A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

dead drop
A dead drop is a location used to secretly pass items between two people, without requiring them to meet.
Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.
A common place is to duct tape the item to the underside of a toilet cover in a public restroom.
A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
