A form of procrastination in which you refrain from doing other work by productively wasting time on only a part of the work you are already doing.
In other words, you are procrastinating by doing work while doing virtually no work.
Boy: What are you doing?
Girl: I have just spent the last hour making my math homework look pretty and neat instead of doing my English homework.
Boy: Wow, at least you're working on something.
Girl: That's productive procrastination for ya.
