An incredibly insane sheep that became so through a parasite which enters the sheep through the skin and penetrates its way into the sheep's eyeballs and brain. From there it continues to gnaw at the wiring inside of the sheep and the sheep's eyes turn into a mass of swirling colors with misshapen and misplaced pupils. It is now MADD MADD MADD.

Term coined by Layne of Nazareth.
Much to the bunny rabbit's dismay, he came to realize upon the day's awakening that his friend Finnius Gregorian Enchanter III, the Sheep of all good Thor's land, had indeed mutated into a Gasheep the preceding night. This realization hit the bunny very hard.. square in the ovaries actually.
