The beauty of the word ooze is not only that it's both a noun and a verb but also that the word sounds like what it means. The ooze on the bottom of the pond oozed between your toes.
When something oozes, it seeps out slowly in an unappetizing way. Cheese sauce oozes out of the container. Sludge oozes out of a treatment plant. Cream oozes out of a tube. Whatever is oozing is referred to as ooze. After an oil spill, a cleanup crew has to clean up the ooze that collects on the shore. It can also be used to describe someone's behavior if it's especially awful. A person who is really bad, for example, can be said to ooze evil.
