Bump Firing
7 Tips on How to Bump Fire - wikiHow - http://www.wikihow.com/Bump-Fire
 * "Bump firing is using a gun's recoil to fire multiple shots using a semi-automatic weapon. This means that you can go "rock n roll" with a legal gun. Note that bump firing can either be done at the hip or the the shoulder. The shoulder method is more accurate. This article discusses the hip-shot method. This method is similar to the way you shoot light-guns at an arcade. "

Dry Firing
"Dry firing is the practice of "firing" a firearm without ammunition. That is, to pull the trigger and allow the hammer or striker to drop on an empty chamber.[1] Dry firing may be mechanically damaging to some firearms – especially rimfire weapons, where the firing pin in most designs will impact the breech face if the weapon is dry-fired. Because of this, precautions (such as the use of "snap caps") need to be taken if such a weapon is to be deliberately dry-fired." 

"It is generally acceptable to dry fire more modern centerfire firearms without a cartridge or snap cap. However, dry firing a shotgun or rimfire firearm can damage the firing pin."
