In Arrested Development, Maeby and George Michael refer to Lucille as "Gangie". The other family members do this too, but usually only when speaking about her to Maeby or George Michael. So this name is clearly being used as a generic word or term of address for a grandmother, like "Grandma" or "Nana". But this usage seems to be unique—or at least, it isn't common enough to have made it into any of the dictionaries I've checked. Which leads me to my questions:
- Has there been any in-universe explanation as to how Lucille got the nickname "Gangie"?
- Is there any out-of-universe explanation for the name? That is, did the creators of the show ever say how they came up with the name?
