Characters light up their houses from the bottom up to the roof (the yard/garden included), decorate and/or illuminate their door and windows; have the biggest, finest tree; fill all their rooms with Christmas wreaths, candles, garlands, tinsel, wrapped-up gifts, stockings, cards, bells, Nativity scenes, Santas, reindeer figures, angels, snowmen, snow flakes, holly, mistletoe, candy canes, peppermints, cookies, gingerbread, gingerbread houses and more. Everything is very bright and very big. One popular colour combination is red and green, often with silver or gold, and there are lots of lights everywhere. Absurdly Bright Light and Christmas Light Chaos might be employed for extra comedy.
Often, there is a contest for the best decorated house, and it's a matter of honour to try one's best to win. In some cases, this might be related to Conspicuous Consumption and showing off. It might be pointed out that more is not always better and that this kind of decorating can be tacky.
These extravagant and overblown decorations have been seen in Real Life, too, but usually people don't exaggerate that much and try to keep the budget down. (Usually.)

- In Elf, Buddy was raised by elves at the North Pole, so over-the-top is the only way he knows to decorate for Christmas. He decorates the toy section at Gimbel's department store so well that the supervisor thinks it's the work of a spy from corporate headquarters, trying to undermine his job. Buddy also decorates Walter's apartment, destroying some of Walter's property in the process, to use the pieces as decorations. He gets a Christmas tree (so big it barely fits into the apartment) by cutting one down from a public park—which, as the movie reminds the audience, is a felony.
- In the parent-centric subplot of Unaccompanied Minors, we see Aunt Judy Davenport's house is decked out in a downright ludicrous amount of decorations, inside and outside, and she implies that her christmas decorating somehow goes beyond that.

- In a rare example from a film that, while it takes place during the Christmas season, is not a Christmas film, Michèle's neighbors Rebecca and Patrick in Elle put life-size illuminated figures of the Three Wise Men on their lawn. While this may not seem like a lot by American standards, the film takes place in France with all the characters being French, from whom we would usually expect more tasteful, restrained displays. (Justified by Rebecca being such a devout Catholic that she and her family take time off to go to Spain and join the pope on the pilgrimage to Santiago de Compostela).
- In the children's picture book The Amazing Christmas Extravaganza, Mr. Merriweather originally intended to celebrate Christmas by decorating his house with a simple string of Christmas lights around the front window.

At this point, he gets carried away with the decorations, adding bigger and more elaborate displays until it ends up taking up the electrical power of the city, leading to a mob led by Mr. Clack to tear the decorations down during Christmas Eve. While Mr. Merriweather is shocked when he discovers the destruction on Christmas morning, it is then that he realizes that fancy displays are not what Christmas is about, and once again his house is decorated with a simple string of lights.

Scully: Yup. All year. Since you always made us take the Christmas tree down the day after Christmas, I'm making up for lost time.

- Goof Troop shows that Goofy clearly went to the Clark Griswold school of decking the house.
- The Kim Possible Christmas Episode begins with the lighting of the decorations at Kim's house, played up with dramatic donning of protective goggles and flipping a Big Electric Switch as if they're activating some mad-science experiment.

- When the late Jennings Osborne put up very elaborate Christmas lights as a gift for his 6-year-old daughter, his neighbors complained. He responded by purchasing their houses and used them to expand his light display, which got bigger every year. Ultimately the display was considered to be a public nuisance by the Arkansas government and the US Supreme Court ordered Osbourne to shut it down. However, after gaining national attention, Walt Disney World in Florida asked the family if they'd like to display their amazing spectacle of lights at their Orlando park. Thus began The Osborne Family Spectacle of Dancing Lights, which lasted a healthy 20-year run at Disney's Hollywood Studios.
