This is a term which generally describes a badly looked after rectum. A hanus anus could be poorly wiped after defication, it may have hemorrhoids or a rash. In some of the worst cases a hanus anus can smell like a repugnant mix of shit and blood.
Those who do not bath frequently or have problems identifying what constitutes a clean asshole after shitting are generally susceptible to having a Hanus Anus.
