I can provide a lot more detail, but here is the short version:
I've posted in various places on TMF, but never written out, the story my wife told me about when she was in college and became a dorm assistant. All the returning and new assistants went on a training retreat, and the first night was devoted to hazing the new members. One of the activities had each new member lay on the floor with their bare feet in a chair. Two (or more) of the senior assistants went to each one and wrote on the soles of the feet, including playing games like tic-tac-toe and writing words and making the person guess what was written. It was all supposed to be innocent fun and my wife told me that she tried her best not to let on how torturous it was for her.
