The history of this word comes from when Thomas' mum, in response to the question, "Does Thomas have a girlfriend?" answered "No, Thomas thinks girls are silly!"

Silli can be used in addition to other words that sound like or ryhme with silli eg. 'willy' or 'little'as long as the other words are said in a high and fast tone.
