Dicktionarian
The type of asshole who posts their name, or the name of someone else and redundant compliments, or insults respectively on the popular website, "Urban Dictionary." This severely clogs up the system, and can usually be noticed by a screen name comprised of spammed nonsense.
Around 90% of the created words on the Urban Dictionary are from complete dicktionarians. Thus making it nearly impossible to get in the 10% of actual slang.
