LOL! For the benefit of the uninformed, this is the phonetic spelling of the Sicilian dialect word for "melanzane", the Italian term for "eggplant."
"Mulinyan" or "da moolies" is Sicilian-American slang for black folks; similar to Jewish people calling African-Americans "schvartzes", the Yiddish word for "blacks."
In and of themselves, these terms are relatively harmless. But they are code words that, once understood, are viewed as racist.
Schvartzes...
I finally get confirmation of what
Mel Brooks says in
BLAZING SADDLES!
THANKS.
