A mix between a stoner and a pothead. A stonehead is a rare breed that is resulted from being a stoner with many pothead friends. A stonehead is usually aware of the name of what they smoke but not of what it is.
Julie can be such a stonehead sometimes. She's so unware of how good her stash is.

An idiot who lays around and bitches all day about things, while getting high, and does nothing themselves. Also, someone who is worthless and has no -real- friends, and is a bum who lives with their parents.
Whoa... Blake is such a worthless stonehead, it's sickening.
