fecalized environment (noun)
Karin McQuillan referring to Africa:  "In plain English:  Shit is everywhere.  People defecate on the open ground, and the feces is blown with the dust – onto you, your clothes, your food, the water.  [A doctor] warned us the first day of training:  Do not even touch water.  Human feces carries parasites that bore through your skin and cause organ failure." (Karin McQuillan, What I Learned in the Peace Corps in Africa, AmericanThinker.com, 2018)
Note:  Seems hotly debated on the internet as to the cause:  Culture, poverty, etc.  In fact, here is an interesting alternative view:  Senegal Is Not A Shithole, (TheAmericanConservative.com, 2018).  I love this line:  "There is no cultural commitment to open defecation."

franchise (noun)
Definition not found; I could not care less about franchising.
Note:  As I have seen this term used, it seems to mean the combined effect of an organization's brand, product quality, reputation, customer good will, and the resulting positive outcome for its business. (RM)
For example:  Apple has a great franchise in North America, and is now working on developing similar franchises in China and India.
The closest definition I have found:
An economic franchise arises from a product or service that:  (1) is needed or desired; (2) is thought by its customers to have no close substitute and; (3) is not subject to price regulation.  The existence of all three conditions will be demonstrated by a company's ability to regularly price its product or service aggressively and thereby to earn high rates of return on capital.
(Warren Buffett, Letter to Berkshire Hathaway Shareholders, 1991)
