When you take a poop and one poop released from your anus floats in the water (forms a floater). Then a second poop, partially released from your anus hangs down and touches the poop in the water, thereby connecting the poop in your butt to the poop in the water, and forming a "poop bridge".

When you take a large, long crap that touches both sides of the toilet bowl, and fails to break in half when the toilet is flushed, leaving the turd high and dry, bridging both ends of the toilet.
Hold up a sec I gotta take a crap. OMG Someone took a bridge poop in here that won’t flush. I’m going somewhere else.
