what is the definition of a rake that is immoral
A man who is morally loose, short for rake-hell. It's an old slang, goes back to Elizabethan times or earlier I think. There's a series of paintings called the Rake's Progress, which shows a young man's descent into depravity. A new broom sweeps clean, but you can have more fun with an old rake.. That one is from an adult fortune cookie.
