In ‘Lancashire Legends, Traditions, Pageants, Sports’ (1873) edited by John Harland & T. T. Wilkinson, we are told that, ‘”Buck-thanging” is a Lancashire punishment still practised by school boys. The offender is taken and placed on his back; four boys then seize each an arm, or a leg, and the person is then swung as high as possible, and then allowed to fall with a heavy bump on the ground. “Stretching” is a variation of this, for there is then no throwing up, but each leg and arm are pulled different ways, in the manner of a rack, so as to produce excruciating pain.’
I wonder if this still takes place. While at school I might have, sort of, been guilty of stretching someone as described above.
