If you drink a lot, eat a lot, and live a wild and unrestrained life, you might be called a libertine.
A libertine is someone who lives life unencumbered by morals. Although it can be used neutrally, often if someone calls you a libertine, they disapprove of your lack of morality. In the 14th century, a libertine was "a freed slave," from the Latin liber, "free." Starting in the mid-1500s, libertine had a religious and political connotation, referring to a group that opposed Calvinism. By the nineteenth century, the word became strongly associated with immorality and debauchery.
