When ones poop piles up to the point it sticks out above the toilet water like an iceberg made of poop.
After taking a dump, husband yells out to his wife
"Honey, come check out this turdberg before I flush."

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!"

A floating piece of human feces, with a density such that 8/9 of its volume is submerged underwater.

I just finished working in the Davis' backyard and came back to my car with the biggest turdberg you've ever seen. I hate winter.
