Being high. The state of being high on marijuana.
"Man did you see peter last night he was all jonned up."
"I'm pretty jonned out right now."
Being wasted beyond belief, punking everything that walks, trying to fight anyone even when you know you'll lose, over and over and over again.
(wake up in a boat of the Gulf of Mexico no matter where you're from) "Wow, I was so jonned last night!"
