A mysterious being, whose identity and motives are unknown, who insists on scrawling on the bathroom walls in shit. The bathroom may be a public restroom, but is often a bathroom at an professional job.
His brown musings maybe actual words like "hello, hi, or turd" and yet are often fecal smearings with no discernable message.
Who are you shithouse phantom? And why have you selected this bathroom as your canvas?!?!
