Well here goes my explanation long ago around 06 I think. My brother show me a video that had a bunch of anime cutscenes with custom made voices, or edited, and you know it sounded pretty lolsh. For example lets say there was a Pokemon scene with actor voices from some other series, and it made it look funny. Hoping that kinda help. Not sure if there is a specific name for those kind of videos. I will still look. Hopefully someone can help me in my quest. It was similar to AMV's, but instead of music it was random stuff that people edited into the clip.
