S-p-e-l-l-i-n-g

So that trick where you spell words that you don't want your child to hear you saying?  Doesn't work with Rachel.  Lori spelled "j-e-r-k" earlier and Rachel wanted to know what word she was spelling and would not let up.  We told her it was a word we didn't want her to hear, but she said she did.  We told her it was a word we didn't want her repeating.  Fine, she wouldn't say the word, but still, what word was it?  And she just kept pestering.  We didn't give in, but she was very insistent.
