Quite how the news of the girl from Porta Westfalica's cosy night-in spread so fast is unclear, reports the Rheinische Post.
But after planning for a couple of her closest friends to turn up for a movie and some laughs, she was soon confronted with a mass of around 80-100 people all expecting to be invited in to curl up on the sofa for a bit of popcorn and a light-hearted flick.
The girl had other ideas. But try as she might she couldn't persuade her unwanted guests to go away. So at around midnight she called the police.
This wasn't the turn of events that the crowd wanted.
When a couple of officers turned up they were met with a hail of bottles and stones and soon called in reinforcements.
Seven more police cars turned up at the girl's house. But even this show of force wasn't enough to intimidate the teenage gaggle. Police had to use pepper spray and dogs to break up the crowd.
A total of 51 warnings were issued at the scene although many more of the uninvited guests fled through the garden.
While there is no evidence yet as to suggest what the movie's on the agenda were, One can only speculate that the prospect of a night of head-to-head Twilight episodes had brought out the wild side in west Germany's youth.
