I'm screwing around in halo reach when i notice in the file browser has a new search bar entitled vorarephila. It doesnt show any pictures or maps and you cant change the search settings. I go online to google the word and its a scientific name for a sexual fetish that involves being eaten alive. even scarier is the wikipedia article that says "Since the fetish is physically impossible to achieve in real life, it is enjoyed through pictures, stories, videos, and video games.[4]" WTF
Assuming you're not trolling, the only way this would happen is if you had searched something into the file browser then saved the search with the title vorarephilia. The title of your search would then appear in a bar under the "new custom search" bar. If you want to get rid of it just scroll down on top of it and press Y to delete.
