Corker is a slang word, a noun meaning "an excellent or astonishing person or thing." An example sentence might be: "All his films have been good, but the latest one is a real corker." When applied to a person it also suggests a bright, lively personality - possibly derived from the 19th century slang adjective corky, which probably came from the idea of a champagne cork popping - a sense of liveliness and celebration.
The word corker is rather old-fashioned now. It was used a lot in the "bright young things" era of the 1920s.
