The creator of the word had the following to say on his contribution to modern vocabulary:
"I didn't want to say 'get whooped' because that was overplayed and I didn't want to say 'get done' because that was Major's thing, so I just said the first thing that came in my head: 'get scrundled.'"
"Won't you take me to...scrundle town"
This word can also be used to describe an extremely small amount of weed in general less than 0.1g.
