The term anal personality, shortened from anal-retentive personality, is a term derived from Freudian psychoanalysis. It refers to a personality that is obsessive about attending to details and minutiae to the point of being incredibly annoying to others and even self-sabotaging through this trait.
An anal personality's penchant for organization is different from OCD. They do not obsess for hours about perfection, they insist on their own idea of perfection and try to impose that ideal on others. We have all probably worked with, or gone to school with, people who are so organized and so attentive to details that they other people crazy. They are also inclined to let everyone know that their ways of doing and seeing things are superior and drive the people around them crazy
