Definition: a dissolute or profligate person
Many people are familiar with the word, rake, from various forms of entertainment, such as Stravinsky’s opera, and a Rex Harrison movie (both called The Rake’s Progress), or a series of paintings by William Hogath (A Rake’s Progress). Spoiler alert: none of these titular rakes come to a happy end. Rake is a shortened form of rakehell, which in addition to having the benefit of being more obscure than rake, also has the delightful adjectival form of rakehelly.
Ye Rakehells so jolly,
Who hate melancholy,
And love a full flask and a doxy;
Who ne’er from Love’s feats,
Like a coward retreats,
Afraid that the harlot shall pox ye.
—The Bladish Briton (song from The Bacchanalian Magazine), 1793
