The act of rolling a blunt with the intent of getting high while acting like a child again, or being high and acting like a child; such as watching cartoons while high, or wanting to get high so the cartoons become more entertaining.
"I was chilling watching some Cartoon Network, and decided to roll a scoobie doobie when my mom walked in"
The term scoobies comes from "Scooby Snacks" and refers to charred bits of herb and ash you may suck in while hitting a bowl. While unpleasant, they are no where near as bad as a flaming scooby which is a still smoldering piece of bud that will scorch the back of your throat.
"Dude, that bowl is almost kicked. If you hit it too hard you'll get some mad scoobies . . ."
