Rake definition:
In a historical context, a rake (short for rakehell, analogous to "hellraiser") was a man who was habituated to immoral conduct, particularly womanising. Often, a rake was also prodigal, wasting his (usually inherited) fortune on gambling, wine, women and song, and incurring lavish debts in the process. Comparable terms are "libertine" and "debauchee".
The Restoration rake was a carefree, witty, sexually irresistible aristocrat whose heyday was during the English Restoration period (1660–1688) at the court of Charles II.
