A now obselete insult used by fans of the New York Yankees
. Prior to the 2004 World Series, the Red Sox had not won a World Series since 1918. Some say that the Red Sox trading Babe Ruth
so that the owner could fund a broadway play was the cause of a curse, which ended the Red Sox dynasty of the early 20th century, and would cause them to lose when they DID reach the World Series. The same people who thought up this 'curse' crap also wear tinfoil hats to protect against government mind control satellites.
Unfortunately for Yankees fans, they will have to think up a more unique insult to cheer at Red Sox-Yankees games at the Stadium, because with the departure of Pedro Martinez, the 'Whos Your Daddy' chant has lost it's meaning.
