Top definition
The absolutely worst insult in the entire history of the universe. This is less than "absolute zero" on the likability scale. If you are ever called a "flaktordion" you should give up on life and even on your very existence. There isn't a single thing in the universe that is, was or ever could be worse than you.
The entire Phelps family is basically made up of flaktordions.
