When an overweight male (commonly between the ages of 5-7) has an autistic outburst mirroring that of someone with schizophrenia. Outbursts usually take place over things that normal people don't get upset about, like what car seat they can sit in. In most cases if you have ever had a triggered fat boy outburst you most likely have no friends and no one likes you.

Guy 2: Wow, how come his parents don't hit him with rocks?
