What does MTV call their funny little mash ups they do with clips from their shows

[unconditionallove1]

to make them funny? You know how MTV takes clips from their tv shows and puts music to them and cuts the videos in a way to make the characters sound funny? What is that called? Or better yet, does anyone know the link on Youtube or something so I can watch them?
