beetus punch
A blow so hard directed toward ones pancreas, that the end result is the development of type 1 diabetes. A beetus punch shouldn't be given if your victim is pregnant or nursing, due to the chance they already have gestational diabetes, or if they have heart disease, high blood pressure, or any amputations... because it is pointless to try and give someone diabetes if they already have diabetes.
I successfully gave someone a beetus punch yesterday, and today they had to schedule an appointment with an endocrinologist.
