There is a (derogatory) jargon term, which I am having trouble recalling, for something (or someone) that is unique, often in an obnoxious or unjustified way. (For example, in a message handling application, a message type that needs special handling when all other messages share a common path.) Does anyone know what it is?
I want to say it's either "butterfly" or "special flower" (or "special _____", anyway), but as you can probably imagine, trying to search on these terms it is extremely difficult to get contextually relevant results. If you can confirm, please cite sources, either examples of other usage, or better yet, a jargon dictionary entry.
