Early compiler writers used the term for languages that used 'call by name' sub-routines (such as FORTRAN) when something like an expression was passed. A 'thunking' routine was built by the compiler to evaluate the expression and pass a variable to the actual called sub-routine. I don't know why it's called 'thunking', but it's not a derogatory term.

I first heard the term in a book on the OS/2 system design and implementation, and I'm sure it was not intended as derogatory.
