found relatively common in rural areas, mainly around southeast Indiana (especially in towns such as Batesville and Brookville), "backroading" is a term used for driving around in an automobile consuming large quantities of alcohol without a designated driver.
"There was nothing going on last night so we just went backroading all night."
"The party didn't start until ten so we just backroaded until it did."
