a coined term denoting the hypotheticalproposition of a total acknowledgment which, when given, would cause everything (i.e. the entire physical universe) to vanish. "Great Okay" is a humorous take-off on "great Amen," an expression used in a poem (and later a song with the same lyrics) called A Lost Chord, by Adelaide Anne Proctor (1825 - 1864). The poem is about a troubled person who, while idly playing the organ, accidentally strikes a beautiful chord which brings calm and quiets her troubles. / "But I struck one chord of music / Like the sound of a great Amen." / She searches again for the chord but can't find it, and thinks that perhaps she will hear it again at death. —SHSBC Binder 12 Approved Glossary
