Mariah Rosem

Mariah Rosem (born Jan 6, 1996) otherwise known as Rose Marks or Mrosem6, is a Wikia user, a YouTuber, and a Deviant who has a soft spot for Buzz Lightyear and Barney the Dinosaur.

Despite her age, she acts very much like a young child, as she thinks the two aforementioned characters are real. She has also been known to take screenshots from movies and pretend she made the pictures. She has been ridiculed for all these reasons, mostly by I Username Everything.

In one of her blog posts, she implies having a foot fetish. Whether or not this makes her related to Dan Schneider is up for debate. In her Christmas 2018 video, she sang a song to Baby Lamb Creations, otherwise known as Simon. She is somewhat similar to MARIOFANadam203204.
