1) A device that attatches/is attatched to a balistic weapon that severely reduces the muzzle flash and sound waves that occur when the bullet is fired. This is possible by giving a large area for the hot gases to expand before it hits the cooler air, and provides an area for the flash to be contained.
2) An assasin that specializes in finding and eliminating a "Rat". Basically, a hitman.

A silencer is a make-shift product to allow quiet, shameless defecations in public toilets.

A silencer is when a person bunches up a bit of toilet paper, and quickly places it in the water retaining part of the toilet bowl.

Thus, was a foreign object (fecial matter) drops into the toilet, there is no splash, and therefore no noise is created, allowing the person to walk confidently out without being given terrible terrible looks.

One downside to this is that it does not protect the person from their own gaseous discharge before the act of defecation.

A handful of toilet paper quickly thrown into the toilet bowl before doing a shit. This is especially useful in a public toilet, to spare your cubicle neighbours and your own embarrasment.
