If your Christmas is going to include the word get-go then your turkey is too large, your anxiety levels are entirely inappropriate for a celebration of love, and you haven't explained to the children carefully enough that if they get up before dark then they might scare Father Christmas off before he's had a chance to drop off the presents.

Word Not To Use Today: get-go. This word seems to have emerged in 1960s America.
