"Hey goomba I love how you dance the rumba But take some advice paisano, learn-a how to mambo.
If you're gonna be a square you ain't-a gonna go nowhere."
Dean Martin, Mambo Italiano.

Goomba
An Italian American, and only an Italian America, who has ties with the mafia or any goodfellas. He is in no way a gangster or a mobster himself. He sits down eating only pasta wearing vinyl suits and massive jewelry
Goomba is the phonetic spelling of the term "cumpà", which is the way people from Southern Italy used to pronounce the word "compare", that is "godfather". From the original sense it was gradually extended to mean a friend, a partner, etc.
Taken from an Italian word meaning friend, the word is mostly used today as insulting term for Italian-Americans. By calling someone a Goomba, you are implying that they have ties to the mafia.
An Italian New Yorker with greasedback hair carrying a baseball bat saying "Hey Tony, get a load of Sammy Sosa over here!" to ever black person that walks past him may be called a Goomba.
