nadger

/nadjr/ , v. [UK, from rude slang noun nadgers for testicles; compare
American British bollixed ] Of software or hardware (not people), to twiddle
some object in a hidden manner, generally so that it conforms better to some
format. For instance, string printing routines on 8-bit processors often
take the string text from the instruction stream, thus a print call looks
like jsr print: Hello world. The print routine has to nadger the saved
instruction pointer so that the processor doesn't try to execute the text as
instructions when the subroutine returns. See adger.
