|Burning the Midnight Oil|
Many thanks to Obscure Word Love for this one:
N. (lew-kuh-bray-shun) 1. The act of lucubrating; laborious work, study, or writing, esp. that done late at night. 2. Something produced by such study, etc.; esp., a learned or carefully elaborated work. 3. Any literary composition: humorous usage suggesting pedantry.I hope my recent lucubrations will be appreciated by those who read them. And now I'm going to go back to estivating.
