To chief is to take an additional hit of marijuana, against the rules of the group, if smoked in a circle. Chiefing is largely considered to be unethical in pothead circles, as most circles hold a rule saying a maximum of two hits should be taken before passing.

Another alternative form of chiefing is done mutually, with two members of a circle taking hits back and forth without passing it to the rest of the group. This is usually done if the entire circle is preoccupied by something else. Like solo chiefing, this is looked down upon, but is less serious as this is more likely to be viewed as a joke.

A chief is an uncool person. A person who might shame you up if you went out to a party with. A chief is someone who might wear distressing attire or carry on in a nerdy or geeky manner. The chief is more than this though, sometimes related to a fool a chief can always be relied on to 'chief' it up.

Chief is often accompanied with a modifyer:

Bare chief
The living chief
