Outside the technical definition, what is the term "Pharisee" synomynous with inside Christian Teachings?

Beyond the technical meaning, what does Pharisee mean or imply within Christian teachings or homiles? What would be its synonymns? It is used quite often, but I am never quite sure what to make of what is being said, especially if someone is being criticized for being a pharisee. From my perspective, it is meant to imply, - Ostentatious - Corrupt - Incredulous But that seems perhaps incomplete, and perhaps not even accurate.
