"I made the name up" ... He made up a racial slur used in a country where his mother grew up... hmmm...

"At the table in Palos Verdes, Calif., Allen's mother, who is 83, said she told her son the truth: That she had been raised as a Jew in Tunisia before moving to the United States. She said that she and the senator's father, famed former Redskins coach George Allen, had wanted to protect their children from living with the fear that she had experienced during World War II. Her father, Felix Lumbroso, was imprisoned by the Nazis during the German occupation of Tunis."

Washington Post Article

"Macaca" is considered a racial slur in francophone African nations, which led to speculation that Allen may have heard the epithet from his mother, a Francophone who grew up in French-colonial Tunisia."
