Chekhov's gun
A literary element that, at first, seems to have no purpose but is later revealed to be important to the plot. This is commonly thought of as a parallel of foreshadowing, but it is more properly interpreted as "do not include any unnecessary elements in a story."
The return of Carmelita Spats in The Slippery Slope after her seemingly unnecessary appearance in The Austere Academy is an example of Chekhov's gun.
"One must not put a loaded rifle on the stage if no one is thinking of firing it." -Anton Chekhov

Chekhov Quickscope
An element introduced then immediately used, usually to dramatic effect.
When an actor is shot in the opening act, with a gun that was introduced shortly before hand, it is a Chekhov quickscope
Chekhov’s Dog
If a film shows a dog more than once (specifically if that dog has a connection to the main character) that dog will then die later on.
I am Legend is a prime example of Chekhov’s dog

Chekhov’s Firing Squad
A Chekhov’s Firing Squad is when a TV show or movie has almost no plot in the first several episodes, and then proceeds to pull all triggers at once. The way that this turns out is a show feeling bland, with presumably filler episodes for most of the season, though these episode actually build foreshadowing and silent plot. These small, unnoticed details go completely unheard or said, until they all hit you at once like a freight train.
“Bro, that show was a Chekhov’s Firing Squad!”
Chekhov's Unregistered Firearm
A dramatic principal that states every element of a story must be completely unnecessary and never called back to.
Season 7 of Doctor Who contains numerous examples of Chekhov's Unregistered Firearm
