Tattoos, especially old school prison tats.

In track, when a runner withdraws from a race before it begins. The term originated from the days when heat sheets were written on paper, and a runner's name would litterally be scratched off in pencil when he/she decided not to race.

Creating music by means of manually moving a record under a stylus. Typically seen in the musical genres of "House" and "Rap". See my Audio example.

With the same intention as cutting, except trying to avoid scarring. The scratcher will usually use something sharp to the touch but not pure metal, for example, a bobby pin without the plastic coating or a safety pin as opposed to a knife, scissors, razor, pencil sharpener blade, etc.
