A term that is used to deffine the sound that a person might make when stoned. This is a combination of screaming and mumbleing. The person experiencing the euphoria might be talking very loudly but one can not distinguish what they are saying. And when one thinks they understand the words being spoken the words make absolutly no sense. This can be highly entertaining or very scary. Scrumbeling only applies to those who are stoned, if you are drunk it becomes bumbleing.
Hey man, Justin just smoked a fat bowl of salvia and now he's scrumbeling, come watch.
