Sort of like the "stupidest thing you heard someone say" thread, but specific to bad RPing. Either godmodding, weird/stupid characters, or general RP-related dumbness.
One time I caught two people godmodding as dragons. I told them to stop godmodding, then went off to my own thing. They continued to godmod, so I went back and told them again. One said, "I did!" I asked him to define godmodding. He said, "It's when you're really big."
I should've banned him right there, but I was being patient that day.
