WDS is an idea of my own that can be applied to assess whether someone is a weeaboo or not. All you have to do is take the following questions and if they are all "yes" then the person is a weeaboo. There is one exception, however. If the person has claimed/claims to be an "otaku" then they are weeaboo - no exceptions. Happy weeaboo hunting!

WDS
1. Has watched anime?
2. Knows a fair amount of Japanese?
3. Is interested in Japan and it's "culture"?
