"Changeover"
The moment at which one projected reel of a motion picture switches over to the next reel. This is done as seamlessly as possible so that the audience does not notice.
"Cigarette burns"
A fictitious term for the circular changeover marks that appear in the upper right hand corner of motion picture film prints. They allow the projectionist to time the moment that one projector switches off and the other switches on, allowing the film to play continuously without a break. In reality, this term is not used in the film industry.
"Hitting rock bottom"
Generally meaning to reach a point in life where one has lost all possessions, status, or wealth. In the film, Tyler shifts the perception of this term to make it something to aspire to. Hitting rock bottom is equated with reaching a zero point in one's life, allowing that person to rebuild themselves into someone more meaningful. See also "Enlightenment."
"Throwers"
A slang term used in the film to refer to airline baggage handlers
"Tiny Life"
A term Jack uses to refer to the single-serving portions of everything from soap to airline food that he encounters during his business travels. This single-serving mentality also refers to people that Jack meets on his travels. They are "single-serving friends."
Chakras
A concept originating from Hindu and Yogic texts. Chakras are points on the human body that correspond to centers for receiving and transmitting different energies. Jack encounters the concept while engaging in guided meditation at the group therapy meetings.
Cinematography
Closely related to still photography, cinematography is the art of camera, camera angle, lens, and lighting choices as related to motion picture production. Cinematography is handled by a Cinematographer, sometimes called a Director of Photography.
Cue mark
Also known as a changeover cue, it is a visual indicator used with motion picture film prints that signals to a projectionist that a reel is about to come to an end. Since films arrive at theaters generally on several reels, this allows the projectionist to change from one reel to the next reel without disrupting the flow of a film. Tyler refers to them as "cigarette burns" though they are not referred to as such in the film industry.
Dark/Black Comedy
A story or elements of a story in which the humor comes from situations that are not normally considered humorous.
Demolition
The act or process of destroying, especially by explosives.
Enlightenment
A spiritual and metaphysical concept applicable in both secular and non-secular settings. Traditionally, enlightenment refers to the comprehension of all things. In a spiritual setting, enlightenment refers to deep insight into the meaning and purpose of all things. Many religions suggest that attaining freedom from desire and all worldly passions, as well as the dissolution of the ego, are necessary steps toward reaching enlightenment. Tyler regularly espouses "hitting rock bottom" as an enlightened state.
Euphoric
An elevated or exaggerated sense of happiness or well-being

Haiku
A short form of Japanese poetry generally characterized by a seasonal reference, the juxtaposition of two images, and 17 morae, viewed as syllables in English, in a 5-7-5 arrangement. Jack composes such haiku poems and emails them to his co-workers.

Rendering
A process by which waste animal tissue is converted to useful material. Rendering generally involves drying the material and isolating fat from the other material, generally through the application of heat. The fat obtained can be used in the manufacturing of soap, candles, and grease. In the kitchen, rendering can be used to convert pork fat into lard, or butter into clarified butter.
Tracking Shot
A type of camera shot in which the camera moves smoothly through physical space. This shot is so-called because the camera is set up on a dolly which rolls along a length of track.
Unreliable Narrator
A narrator in a work of literature, film, or theater whose credibility is compromised.
