The F word

OK tears are rolling down my face. Nikki had me laughing so hard. She came into the computer room in tears crying hysterically she said Ryan called her the F-word. In her little squeeky voice. I was shocked and said what did she call you?? She said she said you are the F-word (just using the letter F), I said what does that mean?? She says F stands for stupid. I could not stop laughing, I know she wanted me to get mad, but I lost it - it was so funny. Maybe she will learn how to spell one of these days. I asked Ryan what the F-word stands for, she also says stupid, neither of them knew the F actually was not the word. OMG......................
