title: What is an anti-pattern?
body: <p>I am studying patterns and anti-patterns. I have a clear idea about patterns, but I don't get anti-patterns. Definitions from the web and Wikipedia confuse me a lot.</p>
  
  <p>Can anybody explain to me in simple words what an anti-pattern is? What is the purpose? What do they do? Is it a bad thing or good thing?</p>
