Baba Vanga (January 31, 1911 - August 11, 1996) also known as Grandmother Vanga, was a mystic who predicted 9/11, Brexit, the rise of ISIS, and even predicted that the 44th president, Barack Obama would be an African-American president of the United States. When she was a child, she was lost by a tornado which lifted her in the air and threw her in a nearby field. Because of that, she could have the ability to see the future. Baba Vanga died in 1996 due to breast cancer.

This is the nick name given to Howard Stern's show long time producer, Gary Dell'Abate, by Howard Stern.
Howard gave him the name when he mispronounced "BabaLouie" an animation that Gary was was collecting. Howard goofed on him all day as usual and they thought it was going to end there. It never did.
It now is a popular term that Howard Stern Show super fans use as a greeting or a sign referring to the show and its antics.
It is constantly used when people prank radio or tv stations on the air or on set and yell baba booey.
