Smart Contract 

Smart Contracts are a tangible expression of the term 'Code is Law'. By coding prerequisite conditions into an algorithmic contract, one can essentially create a self-executing contract, eliminating the need for a middleman and automating the process of trust.

It is a common feature of blockchain and cryptocurrency protocols.

I tried to scam a customer for his money before the GPS logistics system verified delivery of the goods, but the pesky smart contract prevented me from touching their funds!

contra mundum 

Literally translated from Latin, it means "against the world". It has been used to describe maverick, 'lone-ranger' individuals who lack interest in culture and relative comparisons made by people that the individual deems 'ignorant' (which doesn't make them wrong, necessarily).

The character Tyler Durden from the movie Fight Club is 'contra mundum'.

contrabassoon 

Harbinger of doom and destruction. This instrument has the lowest range of any woodwind, along with the contrabass clarinet, and has a sound powerful enough to turn straight men gay, gay men straight, republicans into democrats and atheists into priests. Do not EVER take your girlfriend to an orchestra performance where there is a contrabassoonist, because he will steal your bitch before the end of the symphony's first movement.

Contradicting Contradiction

A reoccurring happening of two simultaneous events with the premise that both events are polar oppossites to one another, where the result of the matter is physically a stalemate but morally, one side prevails glaringly over the other.

Life is a mixture of Contradicting Contradictions, a mixture of Hope and Despair.
