knackers

Wears one out

Knackers is British slang for testicles: I got kicked right in the knackers.

By extension, knackered means exhausted or broken: I'm absolutely knackered after that hike.

The connection is obscure but may relate to the older sense of knacker as someone who slaughters worn-out horses—something knackered is fit only for the knacker's yard.
