Dirty pole is cock. It most commonly means cock that has been shoved in someone's ass, perhaps in anal sex. It can also mean an unwashed, or uncircumcized penis. Once in a while, it mean's Hugh Grant's penis. The term is often used in the phrase "sucking the dirty pole" or "smoking the dirty pole".
My little sister smokes the dirty pole fairly often.
