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*.

Wifi Parasite

People that buy a latte to sit in a coffee shop or similar venue for free wifi.

I walked in to a bagel shop for a bagel and noticed a table full of wifi parasites, laptops open, paper and pens out and pure business discussions flowing.

Parasite 

One who leaches off others whilst pretending to be their friend. Once they have their fill they move on to the next victim.

That Slimbo is a real parasite. Waited till his mate got a big payout then he and his mates bled him white then disappeared.

Parasite privilege

Parasite privilege is when elites weaponize identity politics to deflect legitimate criticism or to protect their class privilege.

Sane person: Billionaires are parasites. No single person can create a billion dollars worth of value, their wealth relies on rampant worker exploitation.

Privileged NeoLiberal: What? You’re not allowed to criticize billionaires, that’s anti-Semitic.

Sane person: You’re disingenuously using identity politics to protect the powerful. That's parasite privilege.
