1. Soul. As defined by Scientology. Derived from the greek letter theta for thought or life or the spirit.
2. Thetans are needed to animate a flesh body.
3. According to Scientology you are full of "body thetans" - degraded thetans who were once people but are now clustered together along with you and inhabit your body along with you. You are the leader of these thetans.

75 million years ago there was supposedly a ruler of this part of the galaxy named Xenu. To cure overpopulation on all the planets he controlled he summoned the people with psychiatric conditions in for an income tax audit. There they were instead paralyzed by injection of an alcohol and glycol mixture into their lungs. They were packed up in refridgerated units and loaded onto space-craft and taken to Earth (called Teegeeack then) and packed around the bases of a few volcanos.

Then their bodies were all destroyed by nuclear explosions. After this the thetans who were flying around in the winds were caught in electronic beams and frozen together in blocks. Then they were taken to huge 3-D cinemas and shown forms of what life should be like on Earth. After that they supposedly clustered together with a lead thetan in charge and they ended up inhabiting bodies in these clusters. Hence although we are a single thetan we supposedly have about 2,500 other lesser "body thetans" attached to our own thetan self.

The dysharmonious relationship between you and your thetans is what causes all sickness and disease in the world.

If you join Scientology, and pay thousands of dollars, you can go through the process of freeing yourself from these body thetans at huge monetary expense.
I know why I have cancer! My thetans are flaring up again. Better fork over some cash to the Scientology folks so that I can be rid of this disease and my entire life inheritance.

Theranos 

A defunct health care corporation invented by Elizabeth Holmes that was once considered revolutionary in conducting blood tests that required only a finger-prick but there was one big problem; it was too good to be true. It was a big sham. The technology was worthless (engineers with their PhD's couldn't get the blood testing equipment to work), the tests were highly inaccurate (one example; a patient complained about ringing in her ears, Theranos test said she was at risk of having a stroke, her doctor thought something seemed off, gave her a real blood test and it turned out the symptoms were just the result of insomnia!), investors were mislead despite a boatload of red flags (Theranos never demonstrated the technology and showed them the labs. Investors just liked the cool idea of a test requiring just a drop of blood), the company was tyrannical chaos and mistreated their employees pretty harshly, etc.

Holmes and her equally scummy partner/sugar daddy Sunny Balwani have been indicted for wire fraud. Just read the book "Bad Blood: Secrets and Lies in a Silicon Valley Startup" by John Carreryrou if you want to get the full details. A must-read.
I'm just glad I never got sick and relied on a Theranos blood test. I might have died!

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
