Word used to describe the inside of a bachelor pad bathroom cabinet/sink that has been left uncleaned for a lengthy amount of time, causing the buildup of toothpaste/hair/shaving cream to be everywhere around and possibly on toothbrushes in this area. This combination, when left untouched for any long length of time can become the consistiency of cheesecake.
