Bum Shock 

Also known as Poo Jabs.

Bum Shock is caused by a confusion at the Sphincter and is recognised by a short attack of pain in the anus. It is ultimately caused by needing a massive poo which hasn't quite brewed.

Ouch, my bum hurts.

You've got Bum shock!

Most bum shacks are either sheds, garages, outhouses or commentary box. Ham Radio enthusiasts like to lure unwilling subjects to the bum shack in order to educate them.
