means To turn rapidly around a center point, or — figuratively — to present information with a deliberate slant that flatters one side.

from From Old English 'spinnan,' to draw out and twist fiber into thread — the work of the spinning wheel. That sense of twisting filaments into something continuous is why we 'spin a yarn' (a tale) and why a 'spin doctor' twists facts into a more flattering thread. The dizzying physical sense — a spinning top, a skater's spin — grew naturally from the wheel's whirl. It's a cousin of German 'spinnen' and Dutch 'spinnen,' all reaching back to a Germanic root for stretching and twisting.
