It means buying everything, like if you were to buy a
computer lock stock and barrel, it would mean you are buying all the parts of

Someone is a flash in the pan.
It means that the person you are describing is flashy and
showy but they really donít do anything. This also originates from a musket.
When firing a musket the hammer comes down and hits the frizzen. The hammer
would have a flint in it so it would make a spark when it hit the frizzen. The
spark would then go into the pan were there was a small charge of gunpowder
which would go off. From the pan, there is a touchhole that goes into the
barrel where the main charge ignites. If there is just a flash in the pan it
means there is a bright spark and a puff of smoke, but if the charge in the main
barrel doesnít ignite, it doesnít do anything. (Refer to diagram)
