Don’t criticize or question the value of a gift you receive. "He complained about the scarf his aunt gave him - talk about looking a gift horse in the mouth!"

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

A gift exchange game.  "I got a singing Santa mug in the white elephant exchange - totally useless but hilarious"

To decorate for Christmas (from the carol “Deck the Halls”). “We spent the weekend decking the halls with tinsel and fairy lights.”

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!”

To eat or drink too much. “I really made a pig of myself at Christmas lunch.”

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!"

Don’t get stressed or upset. “The turkey’s burnt? Don’t get your tinsel in a tangle - we’ll order pizza!”

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

To suddenly stop a habit or addiction. “He gave up smoking cold turkey in January.”

Doing something risky or likely to get you in trouble. "You’re skating on thin ice coming late to the family dinner again!"

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