Crunchyroll: "Starting from a premise of, "There aren't that many otaku girls who can grandly announce to the guy they like, 'I'm an otaku!' right?" Girl Sugoren describes nine ways a girl might accidentally out herself without thinking."
1. Immediately replying "17" when a guy says, "I wonder how old Luffy is...."
2. Calling a cameraman a "kameko" [since that is cosplayer slang]
3. Using net slang in everyday life
4. Referring to an energy drink as a "potion" or some other game recovery item
5. Being unable to sing anything but anime songs at karaoke
