A single fetid mind can log on to Urban Dictionary, make up a "definition" that absolutely no one uses, and UD and search engines such as Google will give it weight it doesn't deserve. Many perfectly fine terms and phrases are tainted because some vulgar kid got to them first. As a writer, countless times you can invent a new term for something, Google it just to be sure the name's not taken by something real, and find that the top results are vulgar garbage with one or two upvotes (and thus not worthy of being remotely close to the top results). This is partially the search engine's fault but UD is also to blame.
