The chan infection

A disease that you get after seeing characters turned into cats/other animals. Symptoms may include:
-making weird sounds in public
-using emoticons like "UwU" in text
-erratic behavior
It pretty much never leaves your mind, and it shatters your brain cells one by one until you get it forever
The only way to cure it: erasing it from your mind by avoiding all reminders of it
