Sudden Onset of Hyper Retardism 

An infectious disease which causes the victim to frequently act in an extremely retarded manner, may it be in the form of making whale noises while clapping their hands like a seal, or staring at the ceiling while drooling helplessly and laughing as if possessed.

Symptoms include, but are not limited to:
* Wailing making whale noises
* Suddenly yelling 'Iowa' in an extremely retarded manner
* Laughing helplessly after making a bad joke or thinking about something remotely dark
* Acting autistic in public
* Making weird noises which include, but are not limited to, 'IOWAAAA', 'HUEEEEE', 'KEKKEKKEK' etc.

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."

What's SOCF?
