do a bone

to smoke a joint, or hand-rolled marijuana cigarette, usually shared between two or more people

the do bone is centrally located immediately above the female and/or male crotchal region - but below the FUPA or GUNT. distance between the do bone and crotchal region may vary but is typically less than one half inch. many are unaware of the do bone's existence due to a combination of factors; such as excessive hair in upper crotchal region or the absence of semi-rough sexual episodes performed in the missionary or pile driver position. in such positions, the do bone of the rowdy sex partners may align, collide, and cause pain while "doing it" - hence the "do bone".
