British CBT
Cock and Ball Torture (CBT) that involves steeping a man's scrotum in boiling water for a minimum of 5 minutes, similar to what the British do with their tea bags.
My dominatrix Betsy insisted that we try regional variations of CBT. She chose Britain, so she performed some British CBT on me. I can't have kids anymore but it's not like I was using my cock and balls anyways.
