A term for getting high on marijuana used in Vermont. Don't ask me why they add the word "up". I couldn't explain it any more than I could tell you how they thought of the expression cabbage night.
A: Man, I can't stay awake anymore. I am about to meet the table with my head.
B: Wow, you must be pretty stoned up.
To get the balls to do something. To gain courage.
He finally stoned up and told the bitch to get the fuck out!
