Scatmanjohnning is the act of serial defecating, ejaculating, urinating and vomiting on or in groceries. Scatmanjohnning can also be performed using a syringe to hide the body substances in the groceries.

Some Scatmanjohns for example stole the hazelnut spread from a local grocery store and filled the glass with feces to hide their crime.
Willy: "Hey, Harold, have you heard of the scatmanjohnning incident of yesterday?"
Harold: "Oh, you mean the guy that replaced the milk with cum?"
Willy: "Yeah, exactly that. Horrible, isn't it?"
Harold: "Scatmanjohnning becomes a bigger threat every day, it seems."
