Why is it inadvisable to plug in and unplug your guitar cord at the guitar end while power is applied to the amplifier?

It will likely cause a nasty buzzing or harsh noise or series of noises while the live cable tip is grounded on something other than the contact inside the instrument. It will not ruin your guitar amplifier nor will it cause the material on the front of the speaker cabinet to tear.
