IBM had programmed to use Urban Dictionary. After having all the words and definitions incorporated into Watson, he began responding to researchers' questions with profanity, leading the programmers to remove it from its memory and adding an additional filter to prevent it from swearing in the future.
In the United States, some state Departments of Motor Vehicles refers to Urban Dictionary in determining if certain license plates are appropriate or not. For example, a man in Las Vegas was allowed to keep "HOE" as his license plate after managing to convince the state, with the use of Urban Dictionary, that it meant "TAHOE", as in the vehicle made by Chevrolet, since that was already taken.

Since 1999 Urban Dictionary has exploded with popularity. Over one million people visit Urban Dictionary every day. Within the first ten years of Urban Dictionary’s existence, it received over five million definitions. At the start of 2014, the dictionary had over seven million definitions, while 2,000 new entries were being added daily. In November 2014, the Advertise page of the website stated that, on a monthly basis, Urban Dictionary averages 72 million impressions and 18 million unique readers. According to Peckham in January 2014, just under 40 percent of the site’s traffic is international, while the site's audience was predominantly male and aged between 15 and 24.
Although the explicit nature of many definitions on the site has led to objections, the site contains many non-explicit definitions. For example, the word "massive" is Jamaican in origin and is used to describe a group or collective. Peckham responded to the issue, stating that people may not be able to understand the meaning of such words without the aid of Urban Dictionary.
