I don't mean the Christmas day super hangover, we've all done that.
Have you ever made such a bollocks of it that it's spoken about in hushed tones?
Mine was a fairly tame temper tantrum at Dbro who left his wife and three kids the week before Christmas.
I was banging the shopping away and lambasting him for being such a huge prick.
Took the wrapping off the frozen turkey so it'd fit the freezer.
Christmas eve got the turkey out to defrost.....of course I'd thrown it away and saved the wrapper 
No one was allowed to mention it. 
Anyone else?
