1. Poetaster: a writer of inferior poetry
2. Catastrophy: a) something very unfortunate or unsuccessful. b) the denouement of a drama, especially a classical tragedy. (here the literary conceit). Greek: kata- ‘down’ combined with strophe- ‘turning’. c) also cf. catastrophy theory and catastrophism (sudden violent and unusual events).
3. Strophe: a group of lines forming a section of a lyric poem. The term originally denoted a movement from right to left made by a Greek chorus, or lines of choral song recited during this. (Hence, backwards writing, against the grain, wrong-headed.)
4. Plus, apropos of nothing but subsequent definition (Oxford Dictionary of English) Stroppy: British. Informal. Bad -tempered and argumentative. (origin. 1950s. Perhaps abbreviation of obstreperous).
