It's an abbrevation for "Kill Fetch Deliver" and used to describe computer games with linear questing and hack and slash, but can also be used to describe plots in movies and/or books.

The abbrevation is slightly negative, but in a sense in the same category as FPS (First Person Shooter).
Did you play any KFD yesterday?
