How it's used

Originally referring to a monk breaking their dietary restrictions, this idiom is now used humorously to describe anyone who breaks a self imposed rule or habit. It is most commonly applied to people who give up on a diet, a resolution to stop drinking, or a commitment to avoid certain activities. The tone is lighthearted and often implies a sense of playful surrender to temptation.

Common mistake

Avoid using this in a serious or religious context, as it is almost exclusively used as a witty or ironic remark about personal habits. It is not appropriate for describing actual religious apostasy or serious moral failings.
