Means - A person who's a know-it-all and a complete cock. Thinks they have the answers to the universe inside their tiny excuse of a brain. Also think they are above other people because of their smattering of knowledge - hence the "penis".
(n) an highly subjective Urban Dictionary entry that rambles on and on for several pages like a State of the Union address instead of being a concise definition appropriate for this website
Basically the even more uncivilized version of Urban Dictionary. It is hidden in the deep dark evil depths of the internet. God have mercy if you stumble upon this evil.
Encyclopedia Dramatica is a site run by middle aged men and 13 year old boys that were banned off of 4Chan, cried rivers of tears, and made ED to feel "special" and "different from 4chan". It's a site that specializes in ridiculing people and making articles about old memes. Most of the time, it tries to be funny but fails..HARD. It's a site so poor, it needs to leech money off it's own members in order to survive. It just shows that it's a terrible site that can't even run itself efficiently. It's nice to browse once in a while, but it sucks to be a member.
