Virus = doctors' Latin for "your guess is as good as mine".

I like the word thanatolithologist precisely BECAUSE it's pretentious. As I said, I can usually tell whether a person has a classical education or is reasonably widely read (and knows at least a smattering of the Greek and Latin words that make up the English language).

My business card reads "Thanatolithologist" -- when I introduce myself, I describe myself as a researcher on gravestones and gravestone carvers with a special interest in ligatures on gravestones.
