B.O.Blivious

People who challenge the conventions of fashion by clashing what appears to be a clean and ironed look with a rank unkempt stench reminiscent of the Bally towel bin.

Unlike the typical unkempt person who knows he's probably a little ripe but just doesn't care, people who are B.O.Blivious are completely unaware of the problem.
