Kick in the knackers, meaning a kick to the testicles of a male. When a boy is kicked in the cock and balls and it hurts like hell, resulting in the boy falling to the ground in pain and rolling around. A kick to balls/knackers is an unfair move.
Jacob and Harry where fighting at school. Harry would have won the fight but Jacob used a kick in the knackers on Harry and Jacob immediately won the fight as Harry couldn’t continue after having his groin attacked so brutally.
