Person 1: "Hey, did you hear about John?"
Person 2: "Yeah, he was fine at the party until he had a Sudden Onset of Hyper Retardism... poor fellow lost it then and there and passed away making whale noises."

Person 1: "I couldn't stop laughing after reading the word 'special assembly' and imagining a bunch of students standing in lines, staring at the sky with their heads crooked, drooling from their mouths and endlessly laughing."
Person 2: "Yeah, well, you had a Sudden Onset of Hyper Retardism. Relatable."

When you are old enough to remember events that happened 10-15 years ago but can't quite remember the exact details of the story. This is usually solved by asking others who were present to fill in the details. This type of dementia can be caused by several factors including drinking, having too many experiences, or by simply not choosing to remember your horrible past.
I can't believe I was actually at a Spin-Doctors concert. Many thanks to my Middle-aged Onset Dementia for helping me not remember that part of my life.
