A bagel one encounters on the ground with a turd placed on top of it. The bagel can be any flavor but needs to be complete and entire- portions of bagels do not count. The location of the bagel is generally the sidewalk, but a turd bagel could theoretically be found anywhere. The turd should be large enough to cover and crown the bagel hole, so it is usually a large dog or human turd.
"Holy shit! Watch out, you almost stepped on that turd bagel!"

Also- Al Franken is a total turd bagel.
