A turd so large that it ends up poking its head above the water in a toilet. Similar to an iceberg, except found in much "shittier" locations.
"Wow, I just took a huge dump and there's a turd that's sticking partway above the water!" "Sounds like you just made a turdberg... fat chance you'll get that sucker to flush!"
