[Named for Captain Gym Z. Quirk, the first to raise it.] “Objection! Assumes organ not in evidence!” Used in news.admin.net-abuse.email to point out that a comment assumes the presence of something whose existence has not been proven, such as a spammer's brain or gonads. This is not used to refer to things that are definitely proven not to exist, such as a spammer's ethics. It's applicable to enough postings there that a poster wishing to raise the objection often need merely say “ObQuirk!”, an instance of the Ob- convention.
