Redneck-engineered urinal is the only thing that makes any sense, right? The shape molded into the porcelain makes me think it’s not a “normal” siphoning rear-discharge tall toilet (though it could be… I’m not a plumber). Still, if you have a slow trickle coming into the tank through that jury-rigged connector where the flush lever should be, and no flapper or working fill valve, then yeah, it could work as a urinal. Wasteful though, and absolutely inviting disaster if a guest needs to poop.
