Conversion Therapy 

Because nobody else actually gave a definition, opting instead to give their opinions, here's the definition I found on Wikipedia:
"Conversion therapy is the pseudoscientific practice of trying to change an individual's sexual orientation from homosexual or bisexual to heterosexual using psychological or spiritual interventions."
Conversion Therapy is indeed a form of brainwashing, but people should know the full definition, not just that it's bad.

Conversion Van 

A full-size van, usually with a completely re-done interior and some external modifications, all of which are done by a company who buys the van new and then re-sells the vehicle to consumers. These add-ons can include everything from blinds to a tv. They almost always have a fiberglass roof that is taller than stock, to make head room and add room for the tv. Many of these vans come stock with middle row seats that rotate, and a back seat that folds into a bed. There are many other great things about conversion vans too.
My friend has got a Honda Odyssey, which has a V6, a TV, lots of storage, and automatic doors. I have a Chevy G20 conversion van, which has a V8, is rear wheel drive, has a TV, even more storage, tons of leg room, and automatic doors are for sissies.

poontang conversion 

noun - a cynical, derogatory, term used to invalidate and belittle someone's acceptance of Christ, after becoming involved with a significant other. Usage requires not actually asking the person in question about their experience, their personal relationship with Jesus, their walk in faith, or any aspect of their testimony. Usually used by those who want to feel intellectually superior to those of faith.
I've known him for years! He just "accepted Jesus" to get into her pants. It's a poontang conversion!

Yeah, I've seen this all before, it's a poontang conversion.

He's saved? I never would have expected that! It must be a poontang conversion.

Word of the Day on October 4, 2026
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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
