Depending on how you look at it: an affectionate moniker, an exact personality profile, or an insult.
The term is used to describe the one person who is the most cuntish, nasty, ruthless, relentlessly rude person in an: apartment block, school, work place, or facebook group etc.
Expression used to describe those who are absolutely annoying, useless, bastards and do not have any chance to show their value because of the huge level of absurdity their lives suffer. They wouldn't even deserve to live in a civilized world since they do not know how to behave. They are complete bawbags worth being puked on.
