Thank you, Alan. What fun!
I liked tacenda and heterophemize, because they're such useful words, and psithurism, because I use susurration and now know there's a more precise word if I can remember it! Quag explains quagmire.
unbepissed: despite the author's incredulity, this might become a common word in our house. I jest, but there's some truth in it. We have an outside cat who does his best to get into the house and wazz on as many things as he can before he's shooed out. His record is two walls and one leather settee in 7 minutes ( that we knew of).
There are maybe 8 - 10 words I might have made a reasonable stab at, but the only one I really knew was jentacular. Backfriend: I'd have guessed the opposite and said it was a good friend who watched your back for you.
