A cheerful way of saying “It’s the festive season.” “Let’s forget our worries - ’tis the season to be jolly!”

To do something completely or enthusiastically. “We went the whole hog this year: decorations, lights, matching pyjamas - everything!"

The more people join, the better it is. “Sure, invite your friends to dinner - the more, the merrier!”

You can only judge the quality of something after you try it. "You say your Christmas cake is amazing, but the proof is in the pudding - let’s taste it!"

To become very bright or happy (literally or figuratively). “He lit up like a Christmas tree when he saw the decorations.”

Doing something that’s clearly against your own interests. "Teachers asking for more exams is like turkeys voting for Christmas.”

Something good happened unexpectedly or earlier than expected. “I got my exam results and passed everything - Christmas came early!”

To leave someone responsible for a problem or task. “Everyone went home early and left me holding the baby with all the cleaning up!”

Feeling sad or depressed during the holiday season. "Some people get the holiday blues when they spend Christmas away from family."

An excuse for indulgence - it’s fine to celebrate or spend a little extra. “Go on, have another piece of cake -  Christmas comes but once a year!”

Warm and comfortable, often indoors in winter. “I love being at home with hot chocolate, snug as a bug in a rug.”

To be mean, stingy, or unwilling to spend or celebrate (from A Christmas Carol). “Don’t be such a Scrooge — it’s Christmas!”

To be extremely full after eating too much. “I couldn’t eat another bite - I’m stuffed!”
