The freakish condition where a sadly obsessed and arguably mentally ill person continually clicks the thumb ratings of accurate Urban Dictionary words they don't like, that most people will never see anyway.
The thumb ratings of Rhondate, ERICTION, Slunthore, Enigman and Cuntrol are clearly indicating a very severe case of Urban Thumb requiring some serious therapy and/or a brutal bitch slaping.
