"A word with a long pedigree in English is 'triskaidekaphobia,' which comes from the Greek phrase meaning 'fear of the number three and ten.' A fear of Friday the thirteenth adds the name of the Norse goddess Frigga, who was the wife of Odin and the mysterious, sometimes scary queen of all the gods."

that her new nickname of "Frigga" is an honorific, but I can't promise I won't occasionally use it as a quasi-homonym in times of frustration.
