Is there a female version of “Tom Dick & Harry”?
No there is no female version – The phrase “Tom, Dick and Harry” is a placeholder for multiple unspecified people; “Tom, Dick or Harry” plays the same role forone unspecified person. The phrase most commonly occurs as “every Tom, Dick and Harry”, meaning everyone, and “any Tom, Dick or Harry”, meaning anyone. The masculine names in these phrase do not in themselves imply exclusion of females, but use of either version when the context implies necessarily being female.
So therefore i claim “Jill, Jane and Megan” to be the female phrase of “Tom, Dick and Harry”.
