The act of remaining in a semi conscious state for a number of hours due smoking good weed. "Stayin' faded" could be defined as little 'out of it', or to the point of complete human disfunction, and total loss of reaction/thought.
Minson(pronounced Minn-Sinn/Minn-Sun) is a noun, used to attract someones attention or start a conversation. It is also an interjection, as it can be used as a form of expression. A cross between the words "son" and "man", turned into "minson" as manson sounds odd and reminds people of marylin manson.
