There was a Krampusnacht in my old neighborhood in DC.
On the Internet, might have been Reddit or MentalFloss.
I believe I’m number six?
Grimm for me, too.
“Carn Evil,” an arcade shooter game from many years ago. Krampus was one of the end bosses. He threw pieces of flaming coal at you, which you had to shoot down to avoid getting hit.
At the time, I thought the game developers had made him up as some kind of wierd evil Santa Claus. (It was that kind of game.) Years later I read about him in a Listverse article on obscure Christmas characters/monsters.
Seven. I guess I should go someplace on the internet and try to figure out what it is, or something.
Saw previews on HULU. First I have heard about it.
Wasn’t Warehouse 13 - although may have been mentioned in passing (no episode dedicated to Krampus that I am aware of)
Likely this one -
Which I had forgotten about. http://www.imdb.com/title/tt1032140/plotsummary?ref_=tt_ov_pl But there they called him an ‘anti-claus’
Long time ago, some German girl at a party told me about him/it. I was pretty miffed that a pretty good friend of mine, born in Germany, had never told me of this amazing character. His excuse was Krampus isn’t a thing in the region of Germany he’s from. Whatever, still disappointed.
I may have heard of it in passing before this, but the first time I heard about Krampus and remembered it in detail was on American Dad. It helps that the episode is called…
Minstrel Krampus…but of course that is because of all of the singing in the episode
I guess I did see it on Grimm but I didn’t make the connection with the movie until others posted it here.
Now that I know what it is, I’ll keep an eye out. I might also see how to work this into a story for my four-year old granddaughter who is SO EXCITED about Christmas…
When I was a very small child. Then again, my mother is German - she told us about the year when she was a little girl that Krampus came to visit her brother because he and one of his friends had been playing Cowboys and Indians and using the dining room table as a teepee and had lit a real, live fire. Because all teepees need a fire. On my Oma’s hardwood floors. In a company house that my grandparents did not own, but were responsible for the upkeep and repairs to.
They had the bad judgment to select the first week of December for their experiment in Historically Accurate Pyrotechnics. Apparently, on Saint Nicholas’ Day*, Saint Nicholas himself made an appearance in the household along with the Krampus. Knocked at the door just after dinner and everything - my grandfather let them in. Saint Nicholas provided a lecture. The Krampus provided an unmerciful beating. Saint Nicholas then provided the other children of the house with an array of presents that was several quite large steps above the level of presents they might have otherwise expected and nothing at all for my very-tender-in-the-behind uncle. My grandfather then escorted Saint Nicholas and the Krampus out of the house. The next day, my uncle’s little friend and partner in the pyrotechnics was escorted by his mother to apologize yet again for his behavior - and he informed the entire household in detail about his own personal visit from Saint Nicholas and the Krampus.
The whole thing made quite an impression on all the children in the village.
My mom found out years later that Saint Nicholas was a buddy of her dad’s, and her father and the other miscreant’s father took turns being the Krampus to deliver chastisement to each other’s kid. They thought the lesson might be more impactful if the illusion that the Krampus was a real thing were maintained - easier to do if your dad is the one who opens the door to him and you can see your disapproving father the whole time and can’t pretend it’s just him in the suit.
*Another German thing, wherein children write their list of things they would like Father Christmas to bring them and then stick them in their shoe overnight, whereupon the lists will be replaced with either an orange and some candy or a piece of coal. The piece of coal is considered to be a bad omen for the forthcoming holiday.
Eight, or did I miss one. Another poll option would have been handy. 
I’d heard of it only a couple months ago. It’s one of the monsters in Game of War.
When I was a kid, but then I pretty much forgot about him. Supernatural brought it all back, though.
Nine.
After a long night of eggnog and fruitcake.
I think I read about it in one of those Xmas around the world articles years ago, along with the Dutch racist tradition and Japan’s weird adoption of Christmas.
Browsing in a bookstore and saw Gerald Brom’s Krampus, the Yule Lord. According to Wiki, it was first published in 2012. Sometime later, I was looking through Wiki’s pages on Christmas folklore, and learned that Brom had not invented it.
