Having many dictionaries available online be it word specific or language, Urban Dictionary has been always useful to me. The description of words which are used in context of speech is quite funny at times and sometimes it sounds like an alien word. Let me come to the usage and interface part of UD on my iPad. It opens up with a minimal web preview look which is good in terms of loading fast with the results, At the same time its quite boring. It seems like you have opened urban dictionary in a mobile view mode. NOT to do much with the options as an application should have apart from the DICE icon at the top right corner of the application which shuffles the search automatically. So far so good. It certainly needs to add some different features as compared to the web Urban Dictionary
