flaktordion

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.

Flactoid 

A muscle on the opposite shoulder of your dominant hand. Bad play in sports is usually because of a pulled/strained flactoid.

Tiger Woods: That was a terrible shot.
Phil Mickelson: I know. I pulled my flactoid the other day.
