When you get mad high and fuck mad bitches. Joycin' is used only when you are incredibly high, so high that you forget everything you were supposed to do that day. Usually used to describe someone who is a lazy piece of shit, or said by people who have been high all day, and proceed to fuck bitches afterwards.
