knee knocker 

A term, which came about in the 1800's, however became popular with soldiers in the Second World War.

A knee knocker is a specific act of casual sex, usually performed in an alley beside or behind a pub/bar/tavern.

The act is performed standing up, with the woman secured against a wall with a combination of the mans upper body and holding her buttocks. The womans legs, usually wrapped around his waist.

This unusual position, whilst having sex results in the knees of the male regularly knocking together (often with some force), hence the term.

Also refer to the term 'knee trembler'.

Knee Knocker 

Knee Knocker is a type of weapon that is shorter than a baseball bat, but long enough to swing at someone's knees. A Knee Knocker will be short enough to be portable, but long enough to reach at the knees of someone and possibly break their legs, if swung hard enough.

Often times, you'll see this being used as a self defense weapon and being at a fixed length. You can find telescoping ones and even some that can be specially designed to impact with the most amount of energy.

This person came up to me and I decided to use my Knee Knocker to knock their knees out.
