Bunglers are people who are clumsy and inept at their job. The term can be broken down into two words: OAFS (4 letters) and SADSACKS (8 letters). OAFS is an acronym for 'Oafish, Awkward, Foolish, and Sloppy' and SADSACKS stands for 'Sad, Apathetic, Disorganized, Sluggish, Apathetic, Clumsy, and Klutzy'. Together, these two words describe someone who is not very good at their job and often makes mistakes.
