Rococo

adj. Baroque in the extreme. Used to imply that a program has become so encrusted with the software equivalent of gold leaf and curlicues that they have completely swamped the underlying design. Called after the later and more extreme forms of Baroque architecture and decoration prevalent during the mid-1700s in Europe. Fred Brooks (the man who coined second-system effect) said:

"Every program eventually becomes rococo, and then rubble."
