Here is another example of a culinary medical term.
QUESTION: What is the relationship between cottage cheese [pictured here, above] and a vagina [pictured here, below]?
Candida albicans is a fungus that is normally found in the vaginas of healthy women, however, in certain circumstances an abnormal overgrowth of this fungus can occur resulting in a thick white curd-like vaginal discharge that resembles cottage cheese in appearance (Achkar JM, Fries BC. Candida infections of the genitourinary tract. Clin Microbiol Rev, 2010 23(2):253-73.).
In this case, the relationship between the vagina and Candida becomes unhealthy.
