a container filled with explosive or incendiary material,
designed to explode on impact or when detonated
by a timing, proximity, or remote-control device

We were told that every village along

the Western Front/Somme battlefields

has an ammunition dump nearby

where farmers can dump unexploded

bombs/ammunition from two World Wars. 

These dumps are cleared every

three or four weeks.


I can’t speak for other parts of the world, however,

Down Under this is also referred to as an old bomb.

Depending on its condition any vehicle

over aout 15 years is a bomb.

And putting a bomb under a person,

usually a subordinate in the workplace,

means a verbal reprimand for poor workmanship.
