The state of being wherein a person is exhausted and unable to think clearly. It is not the same as merely being tired. Being bonjoned means to be tired AND to feel dirty AND to be muddy-headed. A good way to make oneself bonjoned would be to do many exhaustive tasks and then to stay up all night, all after having not showered in a day.
