and you smoked it to the county line.
the place everyone in a dry county (typically in the bible belt)has too go to buy booze, usually results in purchase of massive amounts of liquor at once, and often in drunken driving on the return voyage

The thin ridge of flesh between your ballsac and your asshole.
