When a person jacks off seven (7) times in one day. Each time the person marks a "C" on his hand. Use different colors for different styles. For example with porn, with help, by yourself, upsidedown, etc. A lot of people will ask what the "C's" mean, but you will only have to tell the truth to those people in which you trust.
Chris uses the "Cevans" technique everytime that he jacks off, but only his neighbor actually knows what it truely means.
