A freako is a bad freak. The antonym is feeko. Freakos are not very nice people. They are usually politicians, real estate agents, loan officers, people who work at the metro, Canadians, or car salesmen. Common symptoms of being a freako are talking too much about something pretty irrelevent. Freakos usually have no friends.
