Beached Turd 

When someone defecates in a toilet which has very little water. The poo lands on the edge of the toilet basin and is not completely submerged, creating a deadly stank which diffuses beyond the bathroom throughout the whole house.

Man, can you smell that? I think it's coming from the bathroom downstairs... Tina must have left a beached turd in my toilet.

A big, hard turd laying sideways that hurts like hell to push out.

"Dude, after all that sushi and beer last night, I was shocked to wake up and struggle knocking out a breached turd !"
