hand hack <jargon> 1. (Or "{hand cruft}") To Translate a {hot spot} of a program in a {HLL} into {assembly language} {by hand}, as opposed to trying to coerce the {compiler} into generating better code. Both the term and the practice are becoming uncommon. See {tune}, {bum}. 2. More generally, manual construction or patching of data sets that would normally be generated by a translation utility and interpreted by another program, and aren't really designed to be read or modified by humans.
