I wonder which definition of MOGUL she has in mind? Possibilities, from dictionary.com, are:
Mogul
noun
1.
any of the Mongol conquerors of India who established an empire that lasted from 1526 to 1857, but held only nominal power after 1803.
See also Great Mogul.
2.
any of their descendants.
3.
(lowercase) an important, powerful, or influential person:
a mogul of the movie industry.
4.
a Mongol or Mongolian.
5.
Railroads. a steam locomotive having a two-wheeled front truck, six driving wheels, and no rear truck.
Maybe she's really into guys from India? Or Mongolians? Is it possible that she's a vintage locomotive buff?
