Pandemonium Trigger

Can I have a definition please? Country of origin? Possibly in a sentence? Oh how do I spell this word? The letters of the last are spinning in my mind, causing a traffic jam. Beep, Beep! Get out of the way! You're in my way, you foolish letter A. The confusion takes over my mind and everything's a blur. Do I walk or maybe stop.? Should I turn and Run? No, no, no. Relax and breathe. Picture them in their underware. Oh shoot, that's too distracting. Gross. Open your mouth, let the letters line up, and spill them right out.
