Christmas Eve Eve

This morning I posted on Facebook and Twitter that today was Christmas Eve Eve and it did confuse someone. I am not sure where myself and my sister came up with this one (I think it was mainly her) but instead of calling today the Eve of Christmas Eve, we called it Christmas Eve Eve! I was talking to Russell today on the phone and he had not seen Facebook or twitter and called today Christmas Eve Eve! I know its a strange name for a day but why not! Do you have any strange names for days around Christmas?
