Brotherly constriction
Using a flaccid penis, owned by an individual other than yourself, that is long enough in length to wrap it around your own neck entirely at least two times. The owner of the penis then begins to get hard, strangling your neck. As the penis becomes more erect it will begin to crush you throat like a Boa constrictor, eventually breaking the neck. Usually used in a joking manner referring to suicide or depression.
