In the HBO show, "The Sopranos," the word "mulanyan/s" is frequently used as a racist or deragotary term for African Americans.
In the show, Tony Soprano is infuriated by his daughter Meadow, when he finds out she is dating a boy from a mixed-race (African American and Jewish) family. He tells his therapist that neither one of his sisters would have ever brought a "mulanyan" home when they were growing up.
There are many other references to the term throughout the show, always used by members of the mob but never by other characters. This is an indication of the Mafia's racist mentality.
