A physiological condition that renders the sufferer with profound hyperactivity and spasticity... like after drinking 5 cups of coffee. Possibly named after Hall of Fame baseball player Dick Groat.

This little known disease was brought to the mainstream by a complete episode of 'Curb Your Enthusiasm' being devoted to it. We can thank the honorable Larry David for taking a leadership role in bringing awareness to the public so we can raise money to defeat this life-altering disease.
That girl who is playing the piano way too fast and grunts while she's playing must have Groat's syndrome.

Whoa! She just attached the emcee! Yep, she's got it!
