The term has evolved considerably over centuries. In older slang, it referred to anatomy rather than intellect. Eventually it transformed into one of Britain's favourite labels for somebody behaving foolishly.

Language evolves because people enjoy words that sound funny. "Prat" succeeds because it sounds ridiculous. It practically trips over itself when spoken.
Writers, journalists and comedians have embraced the word because it carries just enough sting without becoming cruel.
