pond scum
Stagnant water film
Pond scum is the layer of algae and other organic matter that forms on the surface of stagnant water, creating a greenish film.
As an insult, pond scum describes someone utterly contemptible—the lowest of the low: That guy is pond scum.
The phrase suggests something slimy, primitive, and worthless.
