slam firing 

when you hold down the trigger of a shotgun and pump it, the gun will fire as soon as the pump reaches the forward position. not recommended because it puts lots of stress on the gun.

A massive group of zombies was approaching, so I decided to start slam firing in order to take out more faster.

jewish filing system 

The term given to the practise of accepting documents for storage (or further reference) when in fact they are just thrown into a pile that is discarded after a few weeks.
Usually the jewish filing system is put into use when documents are "too important" to immediately throw away but aren't important enough to sort for retrieval (as nobody ever asks for them)

The accounts department wants us to keep taxi receipts for possible later use? Sounds like a waste of time, I'll use the jewish filing system"
