faker

https://github.com/stympy/faker

Ruby

A library for generating fake data such as names, addresses, and phone numbers.

Faker::Base.method_missing

You can add whatever you want to the locale file, and it will get caught here.
E.g., in your locale file, create a
  name:
    girls_name: ["Alice", "Cheryl", "Tatiana"]
Then you can call Faker::Name.girls_name and it will act like #first_name
