means To cut or tear something into long thin strips, or—in music and sport slang—to play, ride, or perform with blistering skill and speed.

from From Old English 'screade,' meaning a piece cut off or a scrap, sharing a family with Dutch 'schroot' and German 'Schrot' (small fragments). For centuries it simply meant a torn-off strip of cloth or food; the office paper-shredder lent it bureaucratic menace in the 20th century, while guitarists and snowboarders later borrowed it to mean playing or carving so fast you seem to tear the very air.
