1. Any UrbanDictionary.com definition with an unnecessary and redundant amount of images posted under it. The pictures aren't posted to provide a visual example of the word being defined like other definitions, but rather just so attention whores can post pictures of themselves, their pets, or post (sometimes) funny image macros.
2. Any Urbandictionary entry with at least 18 images, and/or where the images posted all represent the exact same thing.
