On Tuesday it'll be the Autumnal Equinox.
"Equinox" is a contraction of a portmanteau word: it is derived from the Yiddish "Yecch", expressing distaste, coupled with the Teenspeak "inorite", expressing agreement, with the final corrupted "right" replaced with an X representing the stinging corrective "Wrong!"
The word "Autumnal", derived from the Greek root "auto-" and the Middle English "Ummm", refers to a lack of self-knowledge.
And so the Autumnal Equinox was traditionally a time for misplaced unease and self-doubt at the start of a new Academic Year.
For this game, I'd like the players to come up with plausible-sounding, but complete bollocks, derivations and explanations for popular polysyllabic words and phrases.
