What is Black Blizzard?
1.
Large swarms of locusts that sometimes plague midwestern farms by eating all of the crops. They are referred to as black blizzards because there are so many of them that the sun gets blotted out.
Farmer Joe: "Marge there's a storm comin'"
Marge: "That's no regular storm Joe, that's a Black Blizzard full of locusts."
