Consider the final (often rather desultory) addendum or comments made (by one side or the other) after an issue is decided, after an argument is complete.
So, it could be a statement of success (whether snipey or kind), an acceptance and admission of defeat (again whether angry or accepting).
What's the SW for that?
Note that there are plenty of SWs for other "phases" of argumentation. For example, it's clear what "closing comments" ("last chance to wrap before the final decision") or "preamble" is. There are also SWs for witty parts of arguments, silly parts of arguments, and so on.
What do you call the "after-resolution" ejaculations? Cheers
