Troll + Collage = Trollage, a collage to catch trolls.
A mash-up of images, references, and quotes attributed to the wrong people. These are usually taken from movies and shows of the science fiction or fantasy genres, or have a geeky pop culture theme.
The monumental amount of conflicting pictures and erroneous quotes from the wrong characters are sure to elicit corrections from the trolls who don't get the obvious joke.
