Diabetic Rage
When a person (usually male, aged, infected with the beetus, and has been on liberty medical commercials) becomes addicted to ice cream and goes into a "rage" when he runs out.  Usually results in the striking of the wife or dog.
"Last week i ran out of ice cream and struck my wife, then i found out my wife has been dead for 6 years.  WHO THE HELL DID I HIT?!" -- Walter Brimley's case of Diabetic Rage
