A widely ridiculed online forum with a dictionary theming, where all posts are in the style of dictionary definitions with no mechanism for replying. Some users play along and post definitions for words, often deliberately vulgar, incorrect, nonsensical, or filled with lavish praise or emphatic ridicule. Others write very matter-of-fact-sounding essays or swear-filled rants conveying their opinions on subjects, especially controversial ones.
"I sometimes like to look at posts on Urban Dictionary when I'm bored"
"Strange choice but ok"
"Did you know if you look up your name you get an essay about how great of a person you are"
"Yes there's essays like that for every name"
