Amusing extension of the nipple gripple that often got out of hand. On a quiet and rainy lunchtime one boy (usually school delinquant Oliver) would nipple cripple another boy until they gave up and agreed to join the patrol. They would then go and find another boy and nipple gripple him until he also "joined the patrol". This would go on until there was a stupidly large group of boys (often more than thirty) and new boys were becoming increasingly difficult to find. Girls were obviously taboo, because we thought their nipples might come off, and bottles of milk would fall out. We usually stopped when the group was so large that we actually made some poor youth's nipples bleed. Which invariably happened.
