Inception Horn 

The horn featured in the original score for the Christopher Nolan film Inception, composed by Zack Hemsey. The horn takes the form of a mammoth trombone backed up by heavy percussion (often repeated multiple times for maximum results of 'Inceptionation') that is played at intervals throughout the course of the composed piece of music to create a more than dramatic atmosphere, giving the characters a valiant amount of purpose.

Side effects of frequent exposure to the Inception Horn may include "the dream collapsing", "checking your totem" and everything happening in slow motion.

Leonardo Dicaprio: "This was not part of the plan!"
Joseph Gordon-Levitt: "The dream's collapsing!"
Inception Horn: "BWAAAAOORRRRRRRR."
Member of Audience: "OHHHH BOYYYYYY"

Inception Hangover 

A state of mind associated with doing any of the below as a result of just having watched the Christopher Nolan movie Inception:
1. Interpreting real life events as being events in a lucid dream.

2. Calling a real-life person a projection of ones' subconscious mind.

3. Accusing someone of implanting an idea in your head through hypnotic or subliminally charged conversation.

1. Just took an afternoon nap, and I'm wondering if this is a dream within a dream. Argh, still have an Inception hangover.

2. I'm still attached to my ex and can't date other women. She's not dead and this ain't no Inception hangover.

3. I feel like I have no real motives. All my motives are ideas implanted in my head by my friends, family and the media. Gotta get over my Inception hangover.

Incestion 

Getting your own mother pregnant, then getting that daughter/sister pregnant. Therefore, it's a sister within a sister. Inception + Incest = Incestion

Woah, you got your mom pregnant? Then that child? INCESTION!
