He wasn't booed. He was moo-ed. His first name is Mushin. If you are aware of any athlete named Deuce or Lou (as in sweet Lou Whittaker), You'd understand this phenomena.

late 60's early 70's, the Orioles had a mountain of a man, Boog Powell, at first base. He said that as it got later in his career, it got tougher to hear the 'g' at the end.
Now he sells grilled meats (I won't say BBQ cuz he uses direct heat) at the O's games.
BOOOOOOOG! Good times those.... :)
