A manipulative, selfish loser whose sole activities include insulting and injuring his/her friends. Girls, stay away from the male members of this species. Boys, prepare to be annoyed all the time. In general - these jerks are always right all the time and they always find a way to justify even (and espeially) the nastiest behavior possible.
The words that fit perfectly into the song that plays during the Mario Party 7 level with the rocketship.
Often followed by random racial slurs or dirty words such as : cunt, nigger, fag, coon, spic, Tim's mom, your dad blew me, I blew a load on your mom, and I fucked your dog in the ear.
Possibly the most annoying thing that anyone could ever do... but it fits so perfectly.
