A counterintuitive and odd term used by some elderly IT folks as opposite to greenfield or greenfield project. Probably derived from Brownfield land (see wikipedia) or brownfield investment (see google).

It is used also to describe an IT corporate landscape as being a wasteland that has been refactored too many times and that has rabbit holes (e.g. firewall / interface bypass approaches), wormholes (e.g. quantum teleported data from one place to another) and blackholes (e.g. data blackholes where data or events disappears) all over the place.
Our chief Architect should answer the question why "System X" is not fit for purpose/fit for use in <corporate>’s brown field reality.

This crappy brownfield project was handed over to us as a disgrace.
