Catfish, believe it or not, I have witnessed such behavior.
In the case I am thinking of, the individual who becomes upset generally feels unappreciated. This causes her to look for instances in which proper levels of appreciation are not shown. Christmas becomes an exercise in showing appreciation, which must take the form of expensive gifts that are exactly as the recipient wanted.
The funny thing, though, is the person I am thinking of is a huge shopper. She loves shopping herself, which means she owns everything and is impossible to buy for. She also doesn't think shopping is a huge chore, so if someone doesn't spend enough effort, well . . . this shows a lack of appreciation.
My sample size is just one, but it does explain how an adult acts out on Christmas day.
