Nickname for Keystone Ice beer. Usually uttered by people when they have had too much of it. Slurred pronunciation of "ice." When one is extremely drunk from drinking a lot of Keystone Ice, they are said to be "icsched."
"Helmsman", after pounding down Keystone Ices for hours and currently extremely drunk and belligerent under the table on the floor screaming, "Give me another "ICSCH"!"
