A WikiWord is any word that starts with a capital letter and has only lowercase letters until the next capital letter. It must also have two capital letters in it.
A WikiWord then becomes a link to a page, which, if it's undefined, will have a question mark beside it inviting you to define it.
WikiWord, ElPresidente, and WlugBananaRepublic, BillGatesSucks? are all good examples of !WikiWords?.
