Tessorexia Nervosa 

A person suffering from Atypical Anorexia (AAN) must show body dissatisfaction, intentional restrictive behavior, and fear of gaining weight while maintaining a BMI of <18.5 and typically fall within the normal to the overweight range.

HAES-supportive nutritionists, wellness advisors, and other non-physicians from within the industry have bastardized the diagnosis of AAN while attempting to free their clients from “diet culture” and encouraging those to eat “what you want, whenever you want”. This trend harms the person by not acknowledging the self-destructive behaviour inherent in bingeing and using food for pleasure. Many consider this a misclassification of Eating Disorders, primarily Binge-Eating Disorder (BED), in an attempt to separate themselves from the stigma and shame related to gluttony and overindulgence. Unfortunately, this is at the expense of those who truly suffer from AAN since they are already underrepresented in medical literature and considered not severe enough for treatment.

Recently, Tess Holliday declared she was diagnosed with Anorexia at around 350lbs. In contrast to her claims, her social media features a plentitude of sweets, cakes, and takeout consumed on a weekly basis without shame. Such a false diagnosis of Atypical Anorexia is coined as Tessorexia Nervosa. Often individuals who are suffering from Tessorexia claim to be in recovery from Anorexia and any attempt to modify their diet would trigger a relapse causing them to waste away.
I suffer from Tessorexia Nervosa! I’m in recovery from Anorexia! Don’t talk to me about my diet or I’ll starve myself again and it will be your fault!

Nerissa, a calm, caring girl. They are usually confident. They are extremely loyal, especially to friends. If,you have a problem Nerissa's would be the best people to go to. Even though they may not be extremely comfortable with their appearance they are beautiful, not only on the outside but on the inside as well. They are extremely talented, especially in music. If you hand them an instrument with a little practice, in no time they will be a pro.

audiophilia nervosa

Audiophilia nervosa describes the anxiety resulting from the never-ending quest to obtain the ultimate performance from one's stereo system by means of employing state-of-the-art components, cables, and the use of certain "tweaks."

Although the goal is supposedly to achieve maximum appreciation of the music, those afflicted with this condition are merely obsesed with their electronics.
Todd had spent well over $100,000 in speakers,monoblock amplifiers, fiber optic cables, Shakti stones, pre-amolifiers, and other equipment and tweaks. And yet he still wasn't convinced that Diana Krall's voice sounded "silky" enough.

Todd was in deep denial concerning his audiophilia nervosa, and his wife was on the verge of calling a divorce lawyer.

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.
