The Letter C Rule:

You shall add another C in front of the first C if there’s a C already in the other word. Example: Tricky, Sticky, Licky turns into: Triccy, Sticcy, Liccy. If it just does not seem right, add it anyway. It is important that everyone shall follow the C rule. You can also say it out loud, but that is optional. You do not have to say it. ALWAYS type it. If you fail to do any of these things except of saying it out loud, you will be severely punished.

I follow this rule.
