A method of birth control.

The removal of a male's testicles through the ballsack-ular area.

Origin: misunderstanding the term "vasectomy" and assuming that men who no longer wish to produce loin spawn would undergo a physical castration to avoid this.
"My dad had a ballsacktomy because my Mom doesn't want to have more kids. He let the doctors chop his nuts off."
