Paradox Duplicate 

A duplicate created as a result of time travel. When one object travels to another time where that same object also exists, then two of the exact same object occupy the same time. The popular theory is that one of the paradox duplicates is doomed to destruction as a result of the universe attempting to correct this violation of the reality matrix of existence. More pressing is the belief that, were the duplicates to come in contact with one another, it would violate the very basic law of physics that 'no two objects can occupy the same space at the same time', and, thus, unmake the universe.
"That's why i didn't want us to meet, Fry. We're paradox duplicates. The more we stayed away from each other, the better chance we had of staying alive. I guess I was wrong...(cough)"

Social duplication. 

Social duplication is when you talk to someone frequently enough that you start using the same terms and mannerisms as them. Usually spotted in close friends and intimate relationships, both or either of the parties in frequent contact take words and phrases, among other forms of communication and apply it in their conversations. Often, this can have a chain effect, having the people that they talk to also display the passed on mannerisms.
Person 1: Hey, Phill's been talking to John a lot lately and he's starting to talk a lot like him.

Person 2: Must be social duplication.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
