Moogie

From Memory Alpha, the free Star Trek reference.

Moogie is a Ferengi term of endearment for females such as mothers and grandmothers. (DS9: "Family Business", "Ferengi Love Songs", "Call to Arms", "The Magnificent Ferengi")

It is assumed that this term is commonly used to describe Ferengi mothers and grandmothers and is not simply a nickname used solely by Ishka's family. For example, upon the completion of Rom and Leeta's wedding, Nog calls Leeta "Moogie." (DS9: "Call to Arms")
