Polygon soup is a group of unorganized triangles, with generally no relationship whatsoever. If you export geometry out of a 3D modeling package, such as Maya or Blender, you will automatically get polygon soup. As soon as you apply any kind of hierarchical sorting or clustering scheme, then it becomes something else (one example being an octree, a subdivided cube). Any kind of polygonal geometry that hasn't been grouped in any way can be considered polygon soup. Optimized meshes may contain grouped items to make drawing faster.
