Crystal Parasite 

Someone that grows their entire personality off of the lifestyle or personality of someone who is already famous, or some cultural phenomenon, basically anything popular, in a vain attempt to get famous themselves.
For example, any YouTuber that has over 100k subscribers, or maybe even less.
Sometimes this works, but most of the time they just come off as a parasite, leeching off of the success of the person or TV Show or whatever, the "crystal" they "parasite" off of.
Thus they seem instead like talentless hacks with no worth of their own besides what they echo from their "crystal".
Essentially they are a clone of the person, but worse. Much worse.
Person 1: Ugh, that guy's such a crystal parasite, always leeching off of Merg's success.
"that guy": What's up guys, welcome back, to *insert game that Merg's already played here*.

Billy Crystal Jew 

A person that always lets you know that they're jewish no matter the topic of the conversation. Normally a dried up, puffy faced, old jew with
purple blotches on their heads that worships money, gold and jewelry. They also believe they are the 'chosen ones'.
Geez, there isn't a day that goes by that this guy doesn't mention he's a jew, or gives a jewish expression 'oy vey, chutzpah', something to remind you on a daily basis that he is jewish. Damn, I gotta listen to this shit everyday. He's a typical Billy Crystal Jew.

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.
