Experiment of one

I’ve become particularly impressed with AI and especially one called Poe (and its bot assistants). This is an edited definition* of one this AI-powered chatbot churned out in a matter of seconds:

An "experiment of one" refers to a type of experimental design where an individual serves as both the subject and the experimenter. In this type of experiment, the individual tests a hypothesis or investigates a research question by manipulating variables and observing the outcomes on themselves. It is a self-experimentation approach that allows individuals to gather data and draw conclusions based on their own experiences.

Examples of Experiment of One:
1. Personal Health and Lifestyle: An individual may conduct an experiment of one to test the effects of different diets, exercise routines, or sleep patterns on their own health and well-being.
2. Cognitive Performance: Someone might investigate the impact of various study techniques, memory strategies, or environmental factors on their own cognitive performance through an experiment of one.
3. Productivity and Time Management: An individual may experiment with different productivity techniques, work schedules, or task prioritization methods to optimize their own productivity and time management skills.
*************
I can't do better than that, but I will add that this is sometimes abbreviated as "n=1" or "n of 1."

a Grandiose one

To call someone a Grandiose or a Grandiose N****r has nothing to do with the character being grandiose, nor is it a play on their ethnicity. It is simply an expression of exasparation at a friend's behaviour.
synonims include: Ass, the N word, Giggan***a
Bob ate the the last spaghet? Man he's such a Grandiose one

The One-One

In specific reference to a subject, person, and/or place from a previous conversation in time.
After talking about a store in the mall, John tells Kim, "let's go to the one-one."

When referencing a girl that share mutual friends, Kim tells John, "the one-one was looking good tonight."

In correspondence to beer brands as they drive to the liquor store, John tells Kim, I should pick up the one-one.
