A surgical procedure similar to a vasectomy, but performed on a rather large and robust scrotum/testicals. A gentleman with "big balls" would require a Vastectomy.
David: Dr I would like a vasectomy please.

Doctor: OK lets start with a physical exam, please drop your pants.

David: With pleasure Doc.

Doctor: Wow! From the looks of that duffel bag of a scrotum I can see right off that you need a Vastectomy.
