A person who is scared to poop in a public washroom while other people are in it. This person will wait quietly and patiently in their stall until every last person has left before he/she will begin to poop.
Sara ran to the bathroom to go number two, unfortunately for her there were three other women in the washroom and Sara was a closet pooper.

A colleague who poops at work and is damn proud of it. You will often see an Out Of The Closet Pooper enter the bathroom with a newspaper or magazine under their arm. Always look around the office for the Out Of The Closet Pooper before entering the bathroom.
Are you or is someone you know an OUT OF THE CLOSET POOPER? If so, that means that you/they poop at work and are damn proud of it!
