A group made up exclusively of anyone who lets the number of thumbs up/down determine whether or not they think an Urban
Dictionary word is of actual
quality.
Coming from "Urban" as in "Urban
Dictionary" and "herd" as in "herd mentality."
"Hmm, I'm not sure if I think this word is particularly
funny or clever. But wait! It has 650 up votes and 37 down votes. I think I'll give it a thumbs up!"
"
Wow, I think that word is hilarious, but it has 103 up votes and 512 down votes. I guess it isn't funny after all... I'll give it a down vote."
... These are primary examples of
people in the urbanherd.
