sustainability suit

Sustainatarian 

Broadly speaking, the term sustainatarian applies to decision-making based on principles of environmental sustainability and fairness to both humans and animals.

Different than a vegetarian (who may eat factory-farmed dairy), or a vegan (who will not eat animal products of any kind) a "sustainatarian" is a person who eats a mostly plant-based diet with occasional sustainable meat, meaning that it is locally and humanely raised. The term also refers to buying fair trade, organic, recycled, reused and/or reusable food, clothing and consumer goods wherever there is a choice.

"Being a strict sustainatarian, I only buy beef if I can get it from pastured cows raised comfortably on a local small-scale farm".

Substance D 

1. Substance D is a fictional addictive amphetamine-like psychoactive drug, also known as "Slow Death", "Death" and "D", that is depicted in Philip K. Dick's novel "A Scanner Darkly". It's derived from the fictional flower "Mors ontologica".

2. By extension, Substance D can refer to amphetamine (speed).

"What he sold me as 'candy' actually turned out to be 'Substance D'."

This is a more subtle way to refer to amphetamine in a conversation if you don't want to attract too much attention.
