Skratching
manipulating recorded sound via its speed (forwards, backwards, fast, slow, etc.) and volume (smooth fading or choppy). Usually done over a beat to express rhythm and skill. Can also be applied to drum (to make drum beats from skratching), basslines, words, synth noises et al.
All that skratching 's makin' me itch.
