I mean the other names make sense with additional context
Both Tit- and Cock- as prefixes used to mean small (no laughing in the back, please)
And Hoary means grey-haired or old-looking
edit as I had to look this one up: “Booby” is an ellision of “Bobo” - as in “No seas tan bobo” (Spanish) - meaning “silly, naive, dumb…” as they tend to be quite tame birds
I’ve never played D&D ever but the only draw for me would be being a DM. maybe I just don’t know enough about it.
