Stemming from Edric, this word commonly describes one who is stupid, ugly, gay and a loser. This insult is heard rarely but when used can cause serious mental effect on the recipient due to its very harsh meaning. A large piece of crap or coffee stain may also be seen on the recipients face and it is deadly.
